Julius Hemphill - Coon Bid'ness 1975

This historic LP includes a 20-minute performance with altoist Julius Hemphill, trumpeter Baikida Carroll, baritonist Hamiet Bluiett, cellist Abdul Wadud and drummer Philip Wilson ("The Hard Blues") taken from the same session that resulted in Dogon A.D. In addition, there are four briefer tracks that feature Hemphill, Bluiett, Wadud, altoist Arthur Blythe, drummer Barry Altschul, and the congas of Daniel Zebulon. The music throughout is quite avant-garde but differs from the high-energy jams of the 1960s due to its emphasis on building improvisations as a logical outgrowth of advanced compositions. It's well worth several listens. AMG.
