The PianoDuo Takahashi|Lehmann combines intellectual programming with passionate expressivity. Original and adaptation – the lines are blurred: in his Concerto for Two Pianos, Stravinsky has the performers appear both as virtuoso soloists and representatives of an imagined orchestra. The composer’s arrangement of Le Sacre for four hands is a masterpiece in its own right. Arnulf Herrmann’s Hausmusik turns the relationship between original and arrangement upside down, whilst the music which drove Nancarrow to compose for player pianos has been retranslated for four hands by Mikhashoff.
