Guitar is identified on screen as Wesley Plass and bass as Dieter Peteriet, both of whom have plenty of session credits at Allmusic and discogs. Interesting clip - thanks for posting. I'm not too sure about Pickett's histrionics - he certainly has jawdropping control of the altissimo, and he gets the crowd on their feet, but he doesn't make a strong musical statement. The Illinois Jacquet of the 1980s? RT is, as ever, wonderful, but not quite as wonderful as usual.
Fantastic! Thanks for posting this. Dave Weckl on drums, but I don't know who are the bass and the guitar players. This looks like a late 80's or early 90's gig....
