Robyn Schulkowsky, percussion; SWR Sinfonieorchester Baden-Baden und Freiburg; Lothar Zagrosek, conductor / Ostravská banda; Petr Kotík, PeterRundel, Roland Kluttig, conductors.This recording is the first ever devoted to the orchestral music of Christian Wolff (b. 1934) and thus documents a little-known aspect of his wide-ranging work. John, David (1998) introduces in its second part a prominent role for solo percussionist, playing a wide range of pitched and non-pitched instruments, includingmarimba, glockenspiel, a variety of drums, wood and metal instruments and other sources, the exact choice left to the performer. Rhapsody (2009), in contrast, uses instruments of the traditional Western orchestra without percussion, divided into three separate ensembles and reordered into unusual combinations and relationships,both within and between the groups.
