Sinewy guitar lines and elemental percussion are the main ingredients in Japanese trio Up-Tight’s psychedelic slop. The band, which formed in 1992, channels the free-form hairiness of German rock group Amon Düül II, along with the primitive grace of early Velvet Underground. Part of a long line of acidic Japanese acts, Up-Tight delivers epic, mind-melting tracks drenched in feedback and space echo. An exhausting trip, for sure—but for fans of vintage psych, it’s definitely one worth taking. Nods to American garage rock and even Syd Barrett–era Pink Floyd give their music a throwback vibe, with coarse vocal melodies nestled inside jangle-pop chords and skeletal backbeats. But even Syd couldn’t have scaled these freaky peaks: Up-Tight’s buildups are colossal in scale and majestic in scope, with gobs of distorted electric guitar spurting like magma from its musical Mount Fuji. Up-Tight performs with the New Flesh at 9 p.m. at the Velvet Lounge, 915 U St. NW. $6. (202) 462-3213.
