Shakey Graves, aka Alejandro Rose-Garcia from Austin, Texas, plays a gnarly composite of blues and folk as a one-man-band of epic sonic proportions. The sound emitted from his hollow body guitar, mildly distorted amp and suitcase drum belie the young singer’s lean frame. He fingerpicks while keeping time with a double-pedal kick drum, hitting a snare fitted into his suitcase drum and a tambourine fashioned to its side. And when he sings, Rose-Garcia unleashes an unearthly howl.
