At 4 o’clock on a scorching Sunday 
          afternoon, a central London concert hall is one of the last places you’d 
          want to be – indeed, I had turned down a chance of a boat trip down 
          the Thames in favour of John Humphrey’s and Allan Schiller’s piano-duet 
          and piano-duo recital in the Wigmore Hall. Though the Hall – hardly 
          surprisingly – wasn’t packed, the nonetheless sizable numbers who turned 
          up were met with a rewardingly unusual programme.	
        It thus began with the busy textures 
          of Reger’s transcription for piano duet of the Sixth ‘Brandenburg’ Concerto, 
          where the different colours of Bach’s instrumental lines rather get 
          lost in the monotonal sonorities of the piano; it thus becomes more 
          an exercise in polyphonic enthusiasm. Busoni’s imaginative two-piano 
          transcription of Mozart’s Fantasie in F minor, K.608, allowed Humphreys 
          and Schiller to make sense of the texture in a way the Reger had not, 
          and they pushed it to an exciting conclusion. The first half was rounded 
          off with Debussy’s rarely heard En blanc et noir, the sound of 
          two pianos coaxing the composer into unusually rumbustious mood. 
        
        The second half was dedicated 
          to Busoni, and especially one of the polyphonic masterpieces of piano-writing, 
          his Fantasia contrappuntistica, in its fourth incarnation, the 
          1922 recasting of the work for two pianos. It was prefaced with his 
          Improvisation on the Bach Chorale ‘Wie wohl ist mir’, 
          from 1916. It’s not often one gets to watch this work being performed 
          in concert, so it’s fascinating to see how Busoni orchestrates for the 
          sonorities of the piano, how he develops contrasting colours in the 
          two instruments, reserving his strength for the gloriously resonant 
          first full statement of the chorale in both pianos.Humphreys and Schiller 
          judged the pace perfectly.
        
        The Fantasia 
          contrappuntistica is Busoni’s astonishingly inventive creative solution 
          to the unfinished fugue in Bach’s Art of Fugue. There’s little 
          in music as physically exciting as the sound of two pianos on the hunt, 
          but Humphreys and Schiller didn’t give in to the temptation of sheer 
          volume. Instead, they concentrated on the dramaturgy of the piece. It 
          opens (and closes), for example, with the pianos exchanging imperious 
          phrases antiphonally, which Humphreys and Schiller treated as if they 
          were lines from two characters on stage – the Fantasia contrappuntistica 
          requires some attention of its listeners, but this essentially dramatic 
          approach made it both texturally vivid and architecturally clear. 
        
        That was good news; better yet 
          is that Humphreys and Schiller are taking both Busoni works, and others, 
          into the studio in September, to record them for Naxos. It will be worth 
          waiting for.
