Not aware of a Tyner bio - I'd read it. Agreed on the majesty of his Milestone catalog. 'Sahara', his first on Milestone, is a desert island disc for me. 'Expansions' and 'Extensions' on BN and 'Sahara' are the ultimate Tyner for me, but he did so many great albums on BN and Milestone. Saw him in the 70's at the Bijou Cafe, and was stunned live and on record at how he could just eat alive such powerful saxophonists as George Adams, Gary Bartz, etc. Sonny Fortune and young Azar Lawrence seemed to do the best holding their own.
