The groundbreaking UK band Nucleus were one of the very first jazz/rock fusion groups, forming in 1969 and releasing their first album in 1970. During their lifetime, the band recorded 13 albums for labels like Vertigo and Capitol, among others. The band was founded by trumpeter Ian Carr. He recruited musicians for the band in the autumn of 1969. The timing was perfect: the world was ready for Nucleus and other early bands who were combining the energy and excitement of rock with jazz instrumentation, like Miles Davis, Tony Williams' Lifetime and Soft Machine. This never before released concert, recorded May 25th, 1971 and licensed from Radio Bremen, captures the band at an early peak and with an interesting lineup: Carr, Karl Jenkins-piano & oboe, Brian Smith-tenor & soprano sax, flute & percussion, Ray Russell-guitar, Roy Babbington-bass & John Marshall-drums. Most notably, Russell never recorded with the band, and his short tenure with Nucleus was completely unknown until now. Shortly after this recording, the original Nucleus began to unravel and three of the players (Babbington, Jenkins & Marshall) ended up in Soft Machine. This fine slice of vital, exciting, early jazz/rock.
