The video is part of a series featuring more than two hours of playing, discussion and analysis in the ArtistWorks Online Bass School, which is hosted by East.
The premise: Gilbert asks East, who spent several years as Eric Clapton's bassist, what he would do if he were sentenced to a prison term of playing in the key of A for 20 minutes. (Don't worry — the video isn't 20 minutes long.)
East's online bass lessons include dozens of hours of pre-recorded videos and the ability to submit practice clips to East and get video feedback from the master himself.
