"There was a lot that was tricky about playing with [Thelonious Monk]. It's a musical language where there's really no lyrics. It's something you feel and you're hearing. It's like an ongoing conversation. You really had to listen to this guy. Cause he could play the strangest tempos, and they could be very in-between tempos on some of those compositions. You really had to listen to his arrangements and the way he would play them. On his solos, you'd really have to listen good in there. You'd have to concentrate on what you were doing as well."
