I had never thought of the theremin as a serious instrument – just the thing for spooky film music; surely not for a concerto? Then I was intrigued by seeing this BIS recording of Aho’s recent concerto for the instrument and the thought occurred that no-one would ever have thought of the tuba as a proper instrument for which to write a concerto had Vaughan Williams not done so, why not one for the theremin? As it happens, among the many instruments for which Aho has written concertos, there’s one for the tuba.
  		   
  		  Though there are twelve recordings of it, the VW is hardly a piece of essential repertoire but, as Dr Johnson said of dogs trained to stand on two legs, the miracle is not that it was done but that it could be done at all. The Theremin – properly spelled with upper-case ‘T’ because it’s the anglicised version of its Russian inventor’s name – is even less mainstream than the tuba as a solo instrument: so little known in classical circles that one web dealer even consistently misspells it as ‘theramin’ in advertising this recording.
  		   
  		  I didn’t go for the Aho Theremin Concerto at the time of its release, a few months ago, partly because Dan Morgan, who thought the Horn Concerto ‘deeply impressive’ was less taken with the ‘comparatively lightweight’ Theremin Concerto – 
review. Curiosity has finally got the better of me several months later, partly because I don’t know Aho’s music at all well. I took the opportunity at the same time of trying the BIS recording of his Symphony No.11 and Symphonic Dances (BIS-CD-1336 – 
review), first by streaming from 
Naxos Music Library and then, because I was so impressed, especially by the Dances, by downloading from 
eclassical.com (mp3, 16- and 24-bit lossless, with pdf booklet). That’s probably the best place for Aho neophytes to start.
   
  To start the wrong way round, I began with the Theremin Concerto, which is placed second on the recording. I must admit that I had been expecting something in less than perfect taste and there are some strange, even demented noises at times, but this is a composer from whom one expects the unexpected, and I was intrigued by what I heard. It works better than the tuba in the Vaughan Williams concerto, more like Messiaen’s integration of a not dissimilar electronic instrument, the 
ondes martenot into his 
Turangalîla Symphony and other works.
   
  At times the solo instrument sounds rather like an Oriental instrument such as the Chinese 
erhu, with quarter-tones; at other times it sounds like the eerie sound of the birds which accompany Aho’s older fellow Finn Einojuhani Rautavaara’s most famous composition, 
Cantus Arcticus. After all, a Theremin Concerto is no more off-beat than one for birds and orchestra. Whether it will prove as enduring as 
Cantus Arcticus, which now has eleven recordings to its credit in the UK catalogue and to which I regularly return with enjoyment, only time will tell. Though some of it seems just to consist of weird sounds for the sake of making weird sounds, there’s enough that is more substantial to make me suspect that it will.
   
  In case you haven’t yet encountered Rautavaara, a good place to start would be with another BIS recording, of Symphony No.7 (‘Angel of Light’), 
Dances with the Winds (concerto for flutes) and 
Cantus Arcticus (BIS-CD-1038: Lahti SO/Osmo Vänskä – 
review). That, too, is available for download in mp3 and lossless sound, with pdf booklet, from 
eclassical.com.
   
  The Aho Horn Concerto is as impressive as Dan Morgan has described it – I happily refer you to what he has said. I will take up one matter which he mentions because I remember him emailing me at the time to ask if I had experienced similar problems with eclassical.com downloads of BIS recordings, namely the failure of some of the tracks to integrate seamlessly when the music is continuous across tracks.
   
  In the bad old days – not so long ago – you could expect mp3 recordings to drop out briefly between movements. The Windows Media Player even used to introduce inter-track gaps deliberately; though thankfully that has been cured for Windows 8, theclassicalshop.net still warn prospective purchasers to expect it and it remains a problem with mp3 files played in the car on an mp3 CDR – otherwise a good way to get 5 hours-plus on one CD – or via the USB input of an amplifier or player.
   
  I played the Aho recordings in 24-bit and mp3 via Winamp and I’m pleased to report that I experienced no inter-track glitches at all. Given that the free version of Winamp is more than happy to play files up to 24/96 and to burn mp3 and 16-bit lossless files to CDR, I’ve come to use it in preference to any other. On the very rare occasions in the past when I’ve encountered a small glitch, Songbird has smoothed the way, but I haven’t even needed to install it on my current desk-top machine, now well over a year old.
   
  I enjoyed the Horn Concerto and Theremin Concerto more than I had anticipated and, in the latter case, more than Dan Morgan, so I can happily commend this recording for your consideration. The recording is excellent, especially in 24-bit form; even in that format the download price of $15.76 is less than you are likely to pay for the SACD at current exchange rates (£20.59 from one dealer as I write!) You won’t get the video clip which comes with the SACD, but you can watch that on 
YouTube. I’m no great lover of the avant-garde but I enjoyed this recording. Even the comparatively unadventurous may well enjoy this, but they may be better advised to start with the BIS recording of 
Symphonic Dances listed above. If you are not sure, sample the concertos if you can from 
Naxos Music Library or 
Qobuz. They also have the earlier recording.

          Another review ...
          
			Kalevi Aho’s work via BIS has produced 
			some reliably magnificent recordings of equally reliably high 
			quality music. For those in the know each new title is something to 
			be sought out and eagerly snapped up.
This is an intriguing pair 
			of concertos and well up to standard from all concerned. The 
			Concerto for Horn and Orchestra opens with not unfamiliar, even 
			Sibelian sonorities, but with the horn placed off-stage so you think 
			you have to turn the volume up. Long past are the days of 
			conventionally diatonic horn writing such as you would expect from 
			Mozart and his antecedents. That said, in some ways we come full 
			circle with Aho who exploits the ‘out of tune’ qualities of the 
			instrument’s upper partials, resulting in some microtonal effects 
			which remind me of Hermann Baumann’s impressive natural horn 
			performances. Divided into access points which indicate bar numbers 
			rather than movements, this is a work in segments but which runs 
			continuously through its various moods. Aho’s orchestral writing can 
			be tough and muscular, but he retains transparency throughout, and 
			clarity of expression and thought are always to the fore.
			This work was written with 
			hornist Annu Salminen in mind, and her performance is superb. Aho 
			tends not to demand virtuosity for virtuosity’s sake, but you’d know 
			pretty soon if things were going awry. Salminen has a punchy tone 
			and highly expressive phrasing which adds to the magical effect of 
			the sublime final section in which the soloist once again moves away 
			from the orchestra.
The Theremin, developed 
			nearly a century ago in the USSR, reckoned to be the first ever 
			electronic musical instrument, is something you will have come 
			across in film scores for spooky movies of days gone by. Other than 
			the human voice it is also unique in being an instrument you play 
			without touching it, but by interacting with a magnetic field. This 
			provides potentially limitless expressive possibilities, and the 
			concerto starts darkly, with the Theremin engaging with low 
			registers like a double bass. As a soloist further along it has 
			qualities which remind one of some kind of exotic Chinese stringed 
			instrument with a bowed singing character and performing in scales 
			which differ just enough from our boring Western mean-tempered 
			instruments to take us into fantastical worlds.
Filled with gorgeous 
			moments, 
Eight Seasons is arguably less of a concerto, with 
			its tendency to wander through picturesque effects such as those of 
			deepening Autumn, Winter snows and ice, thaw and the return of the 
			sun. Avoiding any reference to Vivaldi’s 
Four Seasons, the 
			Theremin joins and links these effects, but performs less as a 
			musical instrument in its own right than a vehicle for fragmented 
			‘moments’. It does have some gorgeously lyrical passages, but even 
			when let loose in movements such as 
Eisschmelze (Melting of 
			the Ice) it never really seems to break free. This is no doubt an 
			effect of that ‘angularity of perception’ which has us searching for 
			something in an instrument which it delivers in too different a way 
			to have a comparable effect to something like an oboe or a cello. 
			Aho even pits it against the human voice in a movement called 
			Weihnachtsdunkelheit or 
Christmas Darkness and again in a 
			few passages further on. This is the voice of Carolina Eyck herself 
			and these are nice musical touches, but a bit like putting a toy 
			piano next to a Bechstein. The Theremin can do a fascinating job of 
			imitating a singer, but a sine wave will never approach the 
			expressive colours of a good human voice. The thrashing around in 
			the next movement, 
Frostwinter, conjuring swirling winds, 
			also leaves me rather cold.
Don’t get me wrong, 
			Eight Seasons is a fine piece but I don’t feel it is the last 
			word in concertos for the Theremin. I have an instinct which draws 
			me towards a re-thinking of the orchestra when it comes to preparing 
			a work which would allow such an instrument truly to shine. Like 
			Messiaen’s use of the ondes Martenot or Harald Genzmer’s Trautonium 
			it can be much more than a resource for special effects, but its 
			uniqueness is entirely distinctive and an oil-to-water barrier which 
			clamours to be broken down with something genuinely new.
