Like his fellow band members, Green was also adept at other instruments, including mandolin and recorder.

According to a 2008 interview, founding member Phil Shulman said that, despite Green's blues influences, he fit in well with the band's progressive style since Green was "quick on the up-take.

"[1][2] Later on, he was a member of the band Mother Tongue, and also recorded on The Green Album with Eddie Jobson and Zinc, splitting guitar duties with Zinc guitarist Michael Cuneo on two tracks.

Green has worked with Billy Sherwood on a number of projects, including Back Against The Wall (2005) and Return to the Dark Side of the Moon (2006).

Green lives in Princeton, Illinois, United States, with his wife, Judy.
