Hey @jgreiner that probably means you were in school with a friend of mine, the great drummer Rob Avsharian! He was Mark's roommate at Berklee for a couple years. He's a fantastic Detroit/Ann Arbor session dude these days. We lived together for a little bit in Denton.
I studied a lot of Mark Turner for several years and he's been one of my big influences for a long time. He certainly is very much his own thing, built on the foundation of Coltrane and Warne Marsh. Considerable Joe Henderson influence makes sense too, although Mark's sound and approach are so clean and meticulous by comparison. I can hear a progression in his concept between his eponymous album leading to "In This World" and then really evolving by the time "Dharma Days" comes around, and then even further with the "Fly" trio. He's certainly developed his own thing in a beautiful way, very inspiring.
The earliest record I have of him is "Yam Yam," a Criss Cross (I think) record just before he got picked up by Warner Bros. He sounds great on it, as with everything, but it's a considerably different approach from what he does today, much more Trane-ish. But still with tons of his own personality, I think that's been in there the whole time he's recorded, it's just developed more and more prominently as time has gone on.
