The idea for the Kaleidoscope works came from the composers' memories of playing with the prismatic toy of the same name as a child. The toy, of course, consists of colored beads in a tube of mirrors, whose reflections generate complex symmetrical patterns that change dramatically in density and texture as the tube is turned. With these pieces the aim was to emulate such dynamic spatial activity through sound, distributing fragmentary materials in space and immersing the listener in a rich and ever-changing sonic environment. They have been composed for an eight-channel listening environment, the speakers arranged equally in a circle surrounding the audience, and the spatial language consists of peripheral, rotational, oppositional and envelopment activities and relationships (in contrast to left/right and back/front as in stereo works and traditional concert diffusion). The works should therefore be spatially and musically coherent irrespective of audience position or orientation, and listeners should receive similar subjective weightings (relative levels) of front, sides and rear wherever they happen to be situated (even if the positions and trajectories of spatial gestures are perceived differently by each). Peter Batchelor is a composer and sound artist living in Birmingham, UK. He has studied with Jonty Harrison and Andrew Lewis and lectures at De Montfort University, Leicester. Predominantly working with fixed-media, his output ranges from two-channel 'tape' compositions for concert diffusion to large-scale multi-channel installation work.This release of electroacoustic music by composer Peter Batchelor contains the original (and preferred) 8 channel versions of the works (DVD-ROM) along with stereo versions (CD) for easier/speedier listening.
