biosphere Wireless: Live At the Arnolfini, Bristol (CD, £16.95)

1st live album by Norway's Geir Jenssen - recorded in 2007 by Chris Watson & mastered by Touch stalwart BJNilsen. In the early 1990s, he was a pioneer of so-called "ambient techno," but since then, he has refined his sound into something more magnetic & enduring. Here, he incorporates samples of field recordings by Jony Easterby & trumpet by Anders Karlskas, invoking a sparser, more arresting sound.
