This collection of orchestral pieces conducted by David Philip Hefti himself overlaps with a Neos disc of the 38-year-old Swiss composer's music that appeared last year. The sibling pieces Klangbogen from 2009, and the cello concerto Gegenklang, composed immediately afterwards and seemingly continuing the musical argument of its predecessor, are common to both; the remaining pieces here follow the timeline of Hefti's orchestral work right up to last year. Like the earlier two, Changements and Moments Lucides form a complementary pair, the first a dark-hued journey into the orchestral depths that putters to extinction, only to be born again as an aspiring viola line, the second full of bright, translucent images projected on to a background of static harmonies. Last year's Eclairs seems to pack all the essentials of Hefti's styles into a brief (eight-minute) time frame, in a series of 11 self-contained episodes arranged as a frieze.
