Volume 9 of Jazzman's Spiritual Jazz series takes a close look at the deeper side of Blue Note.. - Part 2!  From the experimental avant-garde explored by younger musicians such as Bobby Hutcherson, Joe Henderson and Pete La Roca, to the exciting new developments in modal sounds put forward by stalwarts Hank Mobley, Jackie McLean and Duke Pearson. The music we have selected shows how musicians working with the label responded to a period of dramatic social and sonic change, charting the route toward the esoteric and spiritualised sounds that would dominate the deepest jazz of the 1970s. As ever, Blue Note had lit the path, and this new Spiritual Jazz collection shows that the progressive and underground jazz sound of the 1960s was not only the preserve of obscure artists and private pressings.
