God, I LOVE this band! Their series of albums starting with "E.S.P.", then "Miles Smiles", "Socerer" and "Nefertiti" are among the greatest in the history of jazz.

[1] that quartet of albums simply RULES!!! i was listening to later Tony Williams today - his late 80's/early 90's band on Blue Note, was nothing short of astounding. way too overlooked. i believe Mosaic has released all 5 studio records. i've got 'em all individually on cd, plus the 2cd live in tokyo disc and best of! : )
