 When Rainbow Kitten Surprise convened in Nashville in April to rehearse for its first tour in a while, lead guitarist Ethan Goodpaster had to do some experimenting. It was really fun to go through all these new pedals and effects and stuff to figure out, okay, how do we make this guitar sound like a synthesizer? Goodpaster and his bandmates first got together at Appalachian State, deep in the Blue Ridge Mountains.
