A string trio, its music airbound and weightless, contrasts with a choral-like ensemble to make a lapidary flux of ideas, saying more in an evocative few minutes that many manage in an entire symphony.  I have yet to hear a work by Jonathan Harvey I haven't enjoyed.
The Observer (Fiona Maddocks) May 1999

Hidden Voice 2, scored for an energetic string trio against a weightless, chorale-like background, was ethereal, delicately layered, but in the finish purposeful, as the disparate voices felt their way towards a transforming unity.
