First Miles and Coltrane events for me were at the Plugged Nickel. In 1965 I went (from Iowa City) with JR Monterose to catch the Coltrane quartet - JR was friends with Elvin. My first Miles experience was in 1968 and the band was Shorter, Chick Corea, Dave Holland and Tony. As I left the club that night, Joe Segal stopped me to introduce me to Miles, who was leaning on the bar. Joe said I was a record producer, Miles took my hand and slapped me on my ass.          

RIP, he made fascinating music.

RIP! He was great. And he was still active as far as I know
