IST, configured as the duo of double bassist Simon H. Fell and cellist/percussionist Mark Wastell, performing a virtual quartet at London's Cafe OTO, using using pre-recorded fragments of solo work from late guitarist Derek Bailey and tap dancer Will Gaines, combined with sections of silence of unforeseeable length, and then combined with the live musicians; amazing.

Contemporary composer, improviser and pianist Chris Burn in 4 lively, playful and fasciatingly structured works, as heard in Philip Thomas's renderings: "as if as"; "only the snow"; a transcription of Derek Bailey's "from ten, two, and three" in 6 parts; "pressings and screening" in 4 parts; and "the sky a silver dissonance" with Kate Ledger as a 2nd pianist.
