Percussionist Jon Mueller continues his amazing run of releases (he appears on eight Table of the Elements titles in the first half of 2008!) with Topography, a collaboration with Z'h-based sound and visual artist Jason Kahn. As a drummer, Mueller propels Collections of Colonies of Bees and the occasional guitar army of Rhys Chatham; he also finds time to collaborate with artists ranging from Wilco's Glenn Kotche to Swans' Jarboe. Kahn draws on electronic and acoustic sound sources to create slowly developing compositions imbued with a sense of timelessness. Topography addresses the entity of sound as both a physical and psychological factor shaping our consciousness, and is a remarkable display of electroacoustic finesse.
