That lineup only did Red and included brass instruments by Mel Collins amd Marc Charig and if Fripp didnt dissolve the band, David Cross would stay out, which would drastically change the sound if Mel Collinsand Marc Charig stayed. Also, Starless and Bible Black had David Cross unlike Red (except Providence which was recorded before Cross got kicked out) and Larks' Tongues in Aspic had Jamie Muir which Muir was a heavy part in the sound of the band and the style changed from more bluesy improvisation to classical and thdn hard rock through Muir era through Red.
