Check out my band Mt Adventure
we were just played on UCLA Radio yesterday (The song Here and Now)

This is Mt Adventure in a nutshell:

Rule 1: Only acoustic guitars and wacky(ish) instruments i.e air organ, ukulele, didgeridoo, spoons, banjos, recorders, toy pianos, ocarina, wooden flutes, and whatever else we can get our hands on.

Rule 2: NO electric guitars

Rule 3: Anyone can bring a wacky instrument and contribute to the music/madness
