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.

Live recordings from 1973-74 from the trio of drummer John Stevens, guitarist Derek Bailey, and saxophonist Trevor Watts, dynamic works performed "impromptu" with a wealth of ideas as these innovators demonstrate the skills that helped define them as masterful players.
