In order to pursue these new (for King Crimson) ideas, Fripp first recruited bass guitarist/singer John Wetton (a longstanding friend of the band who had lobbied to join at least once before but had become a member of Family in the meantime). The second recruit was Jamie Muir, an experimental free-improvising percussionist who had previously been performing in the Music Improvisation Company with Derek Bailey and Evan Parker, as well as in Sunship (with Alan Gowen and Allan Holdsworth) and Boris (with Don Weller and Jimmy Roche, both later of jazz-rock band Major Surgery).
