The heavy psych-rockers of Sleepy Sun, drawn together in 2005 by the landscape and general weirdness that is Santa Cruz, California, possess an arsenal of jam-band sensibilities. The sextet's haunting male and female vocals and shredding guitar riffs draw listeners headfirst into an intoxicating, extended musical orgy. Sleepy Sun's debut LP, Embrace (produced by Colin Stewart, known for his work with Black Mountain and Destroyer, among others), is gaining a following in the indie-music bloggerati community. Currently based in San Francisco, the group is hitting SXSW and traveling across the Atlantic for a tour of Europe. But first, the band will share a bill with local acts Olympic Size and the Cherry Tree Parade for a night of polyphonic bliss.
