A merging of free jazz and free improvisation in the UK/US West Coast quintet of legendary AMM drummer Eddie Prévost, guitarist Henry Kaiser on "ismguitar", N.O. Moore on "guitarisism", Blinker Golding on saxophone and Olie Brice on double bass, in a rollicking album of electric jazz recorded in the studio in London for two exhilarating "Doors" of quick shifting improv.

Capturing their 2nd gig together, double bassist Olie Brice and trumpeter Percy Pursglove invited two prominent improvisers who had never played together before — drummer Jeff Williams and tenor saxophonist Paul Dunmall — to join them for a 2020 concert at Cafe Oto in London, presented into two palindromic-ally named and profound improvisations: "Tattarratta" 1 & 2.

Double double bass from the duo of John Edwards and Olie Brice performing live at Iklectik Arts Lab, in London in 2017, a return of sorts as Brice's first live improv gig was opening for the Sunny Murray Trio with Edwards and Bevan; here the two combine, in contrast and confluence as they demonstrate massive technique and concentrative conversation.
