Be prepared for a crazy kaleidoscope of psych-rock madness. The members of the Stillwater band, together since 2005, describe their sound as "hardcore and a little Oklahoma sex rock."

Founders Ryan Hendrix and Nick Turner, a London native, met 12 years ago at Oklahoma State University. Playing mostly local shows at first, the duo evolved to include a drummer and eventually added two more members.

Color is the driving force behind their inspiration. They became fascinated by Sir Isaac Newton's "Theory of Color and Sound" and decided to create albums that channeled a musical interpretation of a specific color. The band's first full-length, 2008's "F, Monday, Orange, February, Venus, Lunatic, 1 or 13," is a representation of orange. The second album, still in production, will be an interpretation of pink.
