A. Nothing wrong with gliding into a tone. But then you have to HOLD that tone.
B. Both Vizzuti and Bergeron play jazz, classical, damn near anything you put in front of them. Wayne's big band work is highly recommended listening for sound, time and phrasing. Maynard called him his most musical lead player, and for good reason.
Finally, your attitude about certain genres of music is represensible to me. If I were to walk into a session and lambast classical music and training I'd be tossed out on my ass. Why? Because everyone I sit next to went to a conservatory, studied the classics and still do. Read the Booker Little interview on Allaboutjazz.com or any quotes from Clifford Brown. They studied the classics and knew their Arbans up and down. Nat Adderley, same thing. Lew Soloff, same thing. Wynton, same. Music is music.
