Hard 'n Phirm - http://www.ateaseweb.com/extra/rodeohead.php Hard 'n Phirm began performing musical comedy together in the Spring of 1994 at UCLA. The next year, they won Spring Sing, UCLA's annual school-wide talent show. Baffled by the cold truth that there is, in fact, no money in the school talent show circuit, they disbanded to pursue other interests, vowing to reunite exactly eight years later. Their debut album "Horses and Grasses" contains songs about The Carbon Cycle, Pi, The Loyal Order of Moose, patriotic dinosaurs, and "Rodeohead," a bluegrass medley of Radiohead songs. They worked very, very hard on it. Hard 'n Phirm are both able and anxious to display their comedy wares for an 18-34 year old audience with a hilarity-smoothie of stand-up, music and multimedia slide presentations. They currently reside in Los Angeles and are nice.
