This first CD by Russian-American pianist Margarita Glebov gives 
                  a potted history of the piano impromptu, from its earliest days 
                  around 1820 to three premiere recordings from the last five 
                  years or so. On the way she avoids the famous and multiply-recorded 
                  exemplars of the genre by Chopin and Schubert. Instead she performs 
                  an extended, varied programme which combines a few reasonably 
                  well-known examples with some rarities.  
                  
                  According to the liner-notes (and the New Grove Dictionary), 
                  the title 'impromptu' was first used by Bohemian composer Jan 
                  Voříšek for a piano piece in 1817, and then 
                  again in 1821 for his op.7, a set of six, of which the attractive 
                  opening track of Glebov's recital is the last. In both cases, 
                  however - and likewise for Schubert's first set, D.899 - the 
                  title appears to have been the inspiration of publishers anxious 
                  to entice prospective amateur players. Nevertheless, a trend 
                  was started and this release follows some of the historical 
                  byways of what turned out to be a very pliable art form. The 
                  disc is subtitled "a treasury of extemporaneous piano compositions", 
                  which is a little misleading, suggesting as it does improvisation 
                  - whereas most of these works were as properly thought out and 
                  composed as any more traditional form. 
                    
                  Not every work is especially memorable - the two by Rimsky-Korsakov, 
                  though as well-crafted as the rest of his music, are too brief 
                  to say very much out of context - his op.11 is properly Four 
                  Pieces and his op.38 two. It is equally fair to say that 
                  there is nothing earth-shattering about any of the works. On 
                  the other hand, almost every impromptu Glebov has chosen is 
                  attractively melodic and, within the constraints of a generally 
                  brief time-span - three to four minutes being a typical length 
                  - often quite freely inventive. 
                    
                  The pieces by Liszt, Dvořák and Fauré have 
                  been recorded and performed many times over, Poulenc less frequently 
                  - Glebov gives a fairly neutral account of these which is unlikely 
                  to strike anyone as lacking in taste or finesse. Three that 
                  will probably be widely unfamiliar are those by Felix Blumenfeld, 
                  Arno Babadjanian and Leopold Godowsky, all exceptional pianists. 
                  Their common features are a minor key and plenty of virtuosity. 
                  The Godowsky, a fourth premiere recording by Glebov, teems with 
                  simmering chromaticism, whereas Babadjanian's Armenian heritage 
                  pervades his own nostalgic work; Blumenfeld's piece goes from 
                  darkness to light and back to darkness in the space of two and 
                  a half minutes. 
                    
                  The impromptus by Cui, Balakirev and Mussorgsky obviously share 
                  a certain Russian essence, but otherwise are fairly different. 
                  Balakirev's torrid Impromptu on Two Preludes by Chopin 
                  is typically demanding and the way he transforms Chopin's material 
                  beguiling. Mussorgsky's Impromptu Passioné is, 
                  unusually for an impromptu, programmatic; it is also strangely 
                  calm for a work entitled Passioné, but lyrical 
                  and comely all the same, as is Cui's - the dramatic key change 
                  for the second section supplying the 'capricious' element. 
                    
                  The Fantaisie-Impromptu by Moszkowski bears a famous 
                  title, but as a work is not as well-known as it ought to be 
                  - possibly the only other recording is Seta Tanyel's ten years 
                  ago on Hyperion's Helios label. Vivid and vivacious, this is 
                  a fond homage to the creator of this 'sub-genre', Chopin. 
                    
                  The last three works in Glebov's programme provide contemporary 
                  takes on the impromptu. In a sense they are giving new life 
                  to a form that is quintessentially 19th century. Russian pianist 
                  Nikolai Mazhara, 2004 winner of the International Prokofiev 
                  Competition, wrote his Impromptu in 2008. In her liner-notes, 
                  Glebov says this 'alternative' spelling is popular in Russia 
                  - which is odd, because Russian uses the Cyrillic alphabet, 
                  and the transliterated Russian word for the musical impromptu 
                  is the linguistic hybrid 'eksprompt'. Language aside, Mazhara's 
                  work is pianistically adventurous whilst being true to the tradition 
                  it draws on. Written in the same year, Albanian-born composer 
                  Altin Voltaj's Impromptu is unorthodox in that it consists 
                  of seven movements, alternately slow and fast, varying in character 
                  but unified by a minor third interval. This highly virtuosic 
                  work is the longest on the disc, and the one with the least 
                  melodic appeal. In a way it is not an impromptu at all, 
                  yet paradoxically it comes closest of any to at least appearing 
                  extemporised. In any case, its considerable invention makes 
                  this quite a treat for lovers of contemporary piano music. Both 
                  Mazhara's and Volaj's pieces were commissioned by Glebov. The 
                  final work is a probably unique Tango-Impromptu by Italian-Norwegian 
                  composer Antonio Bibalo. The tango element lies in the convulsive 
                  rhythm, jumping dynamics and posturing pauses. 
                    
                  Glebov performs admirably throughout on a Steinway D, although 
                  some of the quality of this instrument is lost through the recording 
                  which, though reasonable, tends to sound a little desiccated. 
                  The glossy CD booklet, with a colourful expressionist painting 
                  by Bauer on the front cover, provides a detailed listing and 
                  good quality notes on each of the pieces.
