Demo Master Tape Group is:

Nick Dallett - Guitars and other stringed instruments, mostly, keyboards, drums, and vocals occasionally
Larry Genuth - Drums and vocals, mostly, keyboards, guitar occasionally

DMTG is the name we gave to Nick and Larry working in a multitracked studio environment.
These tunes are largely written in the studio, often with an improvised first track which is then overlaid with more improvisation.

Subdirectories:
1980 - Miscellaneous tracks recorded in the early 1980s.  Not for the faint of heart - there's some really wierd shit here!
Bound For The Promised Land - a 6-song EP written and recorded over a four day visit in 1985 - much more accessible
