Coltrane is my personal favourite musician...period.
You guys into
Blue Trane &
Giant Steps need to get into the transitional material(
A Love Supreme,
Transition, etc) + the later period(
Ascension,
Meditations,
Interstellar Space etc).
Tunes like "Mr. PC" are great...face it, though, it's just a Blues.
Miles makes my Top-10...he was definietly at the vanguard of many a shift in style. His electric stuff gets overlooked by many; I used to blow that stuff off, too...couple years ago, I re-visited most of it. Whew!
