(5 channel)
Anders Astrand (b. 1962) composes for percussion instruments, particularly the vibraphone, which he plays on this recording.  Other instruments are marimba, vibraphone and crotales.  Music includes Wedding March, Walking Mallets, Three Seconds to D, Rauk, and Aurora Borealis.  It's a fascinating look and listen into the world of gentle percussion imaginatively reproduced in multi-channel sound.  Delightful in every way!

CHESKY SACD 230 TT:  50:40

(5/4 channel - Chesky prefers not to use the center and low-frequency channels; the readout is 5 channel, but there are only 4, left & right, front & rear)
Recorded in January 2001, this is a superbly recorded CD of fine performances of these famous choruses.  Although only 4 channel,  the sound surely is special in spatial perspectives.  The extended excerpt from Parsifal is particularly impressive with its bells and offstage children's voices.  The only debit is limited playing time.
