Alto!'s inherent otherness is so engaging it's futile to conjure up fitting adjectives. Suffice it to say that the experimental wunderkinds are on a roll, and the proof is in their new album, LP 3, which sees its local unveiling tonight. The record, which will officially be released on June 17 by Trouble in Mind, is a wormhole of sonic delights. Like a mirror-dimension tribal boogie, "Piece Fourteen" wriggles with synth bloops and whistles, jockeying for position in a bizarro digital rain dance. At just three tracks long, the album boasts long-winded compositions of experimental drones and rhythms, coaxing exciting aural meditations from the spaces between repetitions. "Piece Twelve" starts out starkly, fussing in an Ennio Morricone-style western desertedness. Suddenly the bottom drops out, the guitars become dangerous weapons of sonic bludgeoning, and five minutes of doomy heaviness commence before an ayahuasca cool-down. Alto!'s strongest suit is their unwillingness to be any one thing, and on LP 3 they flaunt this tenet. RYAN J. PRADO
