There are many candidates here..The big round fat classic sound : Ben Webster,Coleman Hawkins, Scott Hamilton and Gerry Mulligan (he played baritone) lyrically: Stan Getz, Cannonball Adderly, Sonny Rollins, Paul Desmond (he's an alto guy) Then there is Coltrane all around and for some very cool, out stuff you could try Ornette Coleman, Eric Dolphy(alto and excellent bass clarinet and flute as well from him) Most of these guys pretty much played tenor exclusively. Too many to list and once again some great players are left off.
