In this web-only video master class, original Tower of Power keyboardist Chester Thompson--who over the past 20 years has played with Santana--explains some of the secrets behind his unique, bubbling, rhythmic Hammond B-3 style on such TOP classics as "Squibb Cakes" and "Knock Yourself Out."

This was one of the inaugural videos when we launched the Keyboard TV site in 2006, and since then, we've subsumed all our video content into this, our main site. A couple of website redesigns later, the Thompson clinic remains one of the most-requested video series for us to bring back. We heard you!

Look for other classic clinics and backstage interviews to be re-upped soon, along with our usual torrent of new video content, in the coming weeks.
