Jamaican alto saxophonist Joe Harriott had a fascinating career in London during the 1950's and 60's - he recorded with big bands, trad bands, vocalists and others, but perhaps his greatest contribution was with his "Abstract Jazz" - much like the Free Jazz experiments Ornette Coleman was making at the same time.  Here is his quintet on a series of albums in the early 1960's with Shake Keane on trumpet, Pat Smythe and Harry South on piano, Bobby Orr and Phil Seaman on drums and others!
