Nucleus first attracted attention by winning first prize at the Montreux International Festival in 1970 for their improvised and integrated music which was an amalgam of jazz and rock. Elastic Rock was their most successful, actually climbing to N°. 46 in the Album Charts. Its cover was the first of many Roger Dean designed for the Vertigo label and it''s content was well received by jazz critics. Ever restless Carr decided to opt for a change in direction after this and spilt up what was arguably the best Nucleus line-up of their time. Highly Recommended.
