Okay guys. You know that vibrato. I've heard it before, but mostly on the ten blow. It is true vibrato, not tremulent. Now, listen to this: http://www.rhapsody.com/william-clarke/now-that-youre-gone/now-that-youre-gone
Just click on the first song, it's free to listen. Listen to the solo, on the seven blow William Clarke does the SAME EXACT vibrato! I always had thought it was beautiful and 'sax-y' sounding. Then when I heard Chris I was like, woah, that sounds like William Clarke.
So...WHO else does it? Anyone? Older guys I mean, pre-1990's perhaps.
I could be very wrong but the solo sounds like Mitch Kashmar is playing it to me. To my ear it sounds to much like Mitch's tongue block playing on the top end, he has a very distinctive vibrato.
