[3] With the Mark Varney Project, consisting of Allan Holdsworth, Brett Garsed, and Shawn Lane, he recorded two albums, Truth in Shredding (1990) and Centrifugal Funk (1991).

[4] Beginning in 1987, he spent six years as a member of the Chick Corea Elektric Band, playing with Eric Marienthal, John Patitucci, and Dave Weckl.

He reunited with the Elektric Band in 2002 and with Corea in 2011 when he joined Return to Forever IV with Stanley Clarke, Jean-Luc Ponty, and Lenny White.

His interest grew out of a desire to transcend the physical limits of the guitar and borrow from other instruments, such as the piano and saxophone.
