This is the DVD by Mike Gordon (Phish). It is sort of a documentary of the Deep End recording sessions. Sort of. It's also sort of Mike's quest to understand the role of the bass player. And it's sort of a tribute to Allen Woody. The Deep End sessions were also a tribute to Woody, the bass player for the Allman Brothers and Gov't Mule. The sessions were two CD's from Gov't Mule featuring a couple of dozen name bass players filling in for Woody, who had recently passed away. The DVD (the film and outtakes) includes interview and session clips of such players as Alphonso Johnson, Bootsy Collins, Billy Cox, Chris Squire, Flea, Jack Bruce, Jack Casady, John Entwistle, Larry Graham, Les Claypool, Meshell Ndegeocello, Phil Lesh, Rocco Prestia, Roger Glover, Tony Levin, etc., etc., etc. I found this DVD to be really cool! Very enjoyable and a bit educational as well! I highly recommend it for bass players. And if your a guitar player, there is of course a lot of Warren Haynes! Among what for me were many highlights: watching Meshell groove!!, watching Casady, watching Entwistle's right hand technique, watching Larry Graham!!, Claypool!, Squire!, watching Glover (I found myself surprisingly impressed with Glover!), and of course Phil - especially his interview parts.
