With Trane, I really like everything he has done. If I’d really had to make a choice I’d choose the Impulse! stuff all of it from Africa/Brass to Interstellar Space.
Coltrane developed in so many ways so rapidly that you could divide his work into more eras. The Miles era, the Monk era, the Prestige sessions, the Atlantic stuff, the Vanguard/Africa/Brass stuff, from Crescent to Transition, Meditations via Ascension to Sun Ship, the Sextet live and his last recordings. Something like that. I really love every one of them but I like the more adventurous stuff most.
