Sleepy Sun / Mammatus — Psych-rock vagabonds and UCSC alumni Sleepy Sun weave interstellar transmissions and dreamy anthems crackling with garage pop furor for a joint-trip through the pastoral wild. Sun-bleached jams burn light and slow across the desert with mind-warping psych contemporaries Mammatus, for a heavy hitting double bill that will pound your auditory meatus into total hypnosis. $7 in advance, $10 at door.
April 6, doors at 8 p.m., show at 8:30 p.m., Moe’s Alley, 21+
Spiritualized — Floating in the swirling milieu of the shoegaze nebula yields more than just your average space junk — somewhere in their Milky Way there’s solid rock and it’s rolling toward a galaxy near you. With autoharp and horns strapped firmly into this space-rock suit, Spiritualized tours your sonic sphere with thrumming strings and crystalline pop melodies aerodynamic enough to ride FM airwaves to the stratosphere and beyond. Ladies and gentlemen, cosmic feedback doesn’t pop or hiss, it drones and tremors with lo-fi atmospherics, so fasten your seat belts and don’t get tripped up by this sonic boom. $28 for general admission.
April 11, doors at 8 p.m., show at 9 p.m., Cocoanut Grove Ballroom, 21+
Porter Chalk Festival 2013 — The artists and surrealists of Porter and beyond are going ground-level to render some solid works of art. Head out to the sidewalk strip this weekend as a participant or purveyor and drink in these smooth renderings delicious enough for multiple rounds. This event is open to all students — chalk and snacks will be provided for the artists. Professional chalk artist William Zin will be creating a piece and leading a workshop, chronicling his experience in the concrete jungle of street art, so ditch the trees for a day to come soak up the sun and sediment with fellow chalk enthusiasts.
April 6–7, from 9 a.m. to 5 p.m., Porter College
