Listening to some recent downloads from emusic.com, I came across Bardo Pond's 21 minute version of Funkadelic's Maggot Brain, arranged for guitar and flute. What a great version this is of a truly great track!
This prompted me to have a look for some other versions. There is Govt Mule's bluesy version, which is pretty good, and several clips featuring Eddie Hazel, who wrote the track. But my current new favorites are the Michael Hampton / George Clinton / Lily Haydn version from the Montreux festival in 2004
and the Praxis version (also featuring Lily Haydn) also from 2004
Which reminds me - I have about a dozen Buckethead cds that I haven't really listened to properly yet
