The composer, conductor and pianist Viktor Ullmann showed great musical promise at an early age; with Arnold Schoenberg and Alexander von Zemlinsky as his teachers in later life he embarked on a varied career that continued while he was interned in Theresienstadt from 1942 to 1944. Just a few months short of war’s end he was sent to Auschwitz-Birkenau, where he perished in the gas chambers. It’s a wretched and wrenching tale that’s made all the more remarkable by the fact that Ullmann remained defiantly creative to the very end.
 
This music was largely unknown until Decca’s enterprising – and pivotal – Entartete Musik series of the 1990s. Among the first releases was Ullmann’s satirical opera 
Der Kaiser von Atlantis, composed in Theresienstadt a year before his death. It alerted me – and, I suspect, many others - to the composer’s shocking talent, which shines through in the works on this BIS twofer. It’s sobering to read pianist Christophe Sirodeau’s booklet note in which he lists the members of his mother’s family (Fuchsmann) who died in Auschwitz and Sobibor. The dates and convoy numbers are particularly chilling, as they remind us the Nazis were just as efficient at bureaucracy as they were at mass slaughter.
 
There are rival recordings of the Ullmann sonatas from Robert Kolben (Koch), Gregor Weichert (CPO), Jeanne Golan (
review) and Maria Garzón (
review); only the Golan contains all seven sonatas. Nevertheless, all are welcome evidence of a continuing interest in Ullmann’s oeuvre, and BIS – well-known for their exploration of more peripheral repertoire – must be applauded for keeping up the momentum. In addition to completeness bang-up-to-date sonics makes this newcomer look very competitive indeed.
 
          As Sirodeau points out in his booklet essay the first four sonatas are 
          – in order - tributes to Mahler, Janáček, Mozart and 
          Bartók. 
Sonata No. 1 has a startling lucidity 
          that blends Schoenbergian economy with the harmonies one associates 
          with the likes of Scriabin. Sirodeau’s fine pianism – well 
          caught by the engineers – is also an amalgam in that it combines 
          clean, crisp playing with flashes of surprising inwardness and lyricism. 
          Pedagogic studies these aren’t, and the second movement of this 
          sonata, subtitled 
In memoriam Gustav Mahler, has a haunting 
          simplicity that’s deeply affecting. Sirodeau evinces a fine ear 
          for colour and rhythm – splashes of one, fragments of the other 
          – and his micrometer-like calibration of dynamics is exemplary.
 
          
Sonata No. 2 confirms these as works of considerable 
          confidence and purpose. The Moravian folk tune at the heart of this 
          piece – the link to Janáček – has all the freshness 
          and vitality that one hears in the latter’s 
On the overgrown 
          path (
review)
. 
          Even the closing 
Prestissimo, with its obsessive figures, is 
          full of invention and interest; indeed, Sirodeau lifts and aerates this 
          music in the most delightful way. I fancy there’s a dry wit at 
          work there too. In any event, this pianist displays a masterly control 
          – and understanding - of the score’s content and style that 
          would be very hard to match.
 
          The mellifluous character and Mozartian themes of 
Sonata No. 
          3, deftly plaited with music of sudden sinew, is another of 
          hybrid that shows Ullmann’s command of competing idioms. Sirodeau 
          is similarly well attuned, so that all these elements are explored to 
          the full. His touch in the surging 
Scherzo is particularly 
          impressive, as is his ability to tease out and animate Ullmann’s 
          lively tunes. The finale encompasses so much – classical proportion, 
          romantic ardour and a knowing modernity that owes more to the café 
          than the concert hall. As before Sirodeau yokes it all together with 
          ease.
 
          The first disc ends with 
Sonata No. 4, dedicated to 
          Ullmann’s fellow internee Alice Herz-Sommer, who died in January 
          2014 at the remarkable age of 110. And what a tribute it is; eloquent 
          in the 
Allegro vivace, gentle but firm in the 
Adagio, 
          and fearless in the finale. Sirodeau imbues it all with a spontaneity 
          and sparkle that will perplex those who are unfamiliar with this composer 
          and expect something fierce and unremitting. Indeed, in Sirodeau’s 
          hands this music is rendered accessible in the best possible sense; 
          that will surely help to win more converts to the composer’s cause.
 
          The second CD contains the remaining sonatas, all of which were written 
          at Theresienstadt. Perhaps most poignant is 
Sonata No. 5, 
          subtitled 
Von meiner Jugend (From my youth). From the firm 
          stride and confidence of the 
Allegro con brio – its extrovert 
          character is tempered with moments of surpassing tenderness – 
          to the pensive circularity of the 
Andante – Piú adagio, 
          Sirodeau displays an unwavering instinct for mood and phrase. The giddy 
          little 
Toccatina and the 
Serenade are deftly done, 
          the latter infused with a bracing, tangential strangeness. This is such 
          a well balanced and sophisticated recording; indeed, the Steinway D’s 
          range and richness of tone are caught with a fidelity that one associates 
          with Hyperion’s best piano offerings.
 
          The kaleidoscopic writing of the 
Allegro of the 
Sonata 
          No. 6 contrasts nicely with the glittering 
Allegretto 
          and 
Presto that follow; remarkably for music of such compactness 
          it teems with incident. 
Sonata No. 7, dedicated to 
          three of Ullmann’s five children, has a nursery-like innocence 
          that’s apt to grind against a darker world of adult experience. 
          It’s another of those pieces that reconciles antinomies in a seamless 
          fashion. It all flickers past in a zoetrope of conflicting emotions; 
          these fleeting reminiscences and musical quotations drive home the composer’s 
          steadiness and stoicism in the face of such terrible adversity.
 
          After that minor masterpiece, so exhaustively explored, the earlier 
          
Variations and Double Fugue on a theme by Schoenberg seems 
          almost aphoristic by comparison. Sirodeau conjures a mix of dark sonorities 
          and light, elusive phrases. Even though Ullmann’s in abstract 
          mode Sirodeau taps into a vein of poetry here; as before this intuitive 
          artist proves a reliable and illuminating guide to these scores. His 
          liner-notes are similarly reassuring in their detail and authority.
 
          This complete set of sonatas is a significant addition to the Ullmann 
          discography. Sirodeau certainly digs deeper than Jeanne Golan does – 
          he’s better recorded too – but I suspect some will prefer 
          Golan’s clear, finely wrought playing style. Trouble is, now that 
          I’ve heard Sirodeau nothing else will do.
           
          Deeply penetrating performances; a new benchmark has been set.
