Nucleus

Nucleus was a British jazz-rock group formed by trumpeter Ian Carr (1933-2009) after he left the Rendell-Carr Quintet. The band was active in changing line-ups from 1969 to 1989 and mixed modern jazz improvisation with electric instruments and rock rhythms. Nucleus is best known for its 1970 debut Elastic Rock and for winning first prize at the Montreux Jazz Festival in 1970. The first line-up of Nucleus had Ian Carr, Karl Jenkins, Brian Smith, Chris Spedding (guitar), Jeff Clyne (bass) and John Marshall (drums).
