Psych-rock quartet Static Mountain lift off from an earthly summit through the upper atmosphere and into the unknown. However, the launch isn’t a rough rocket blast that shakes your core. It’s a smooth venture – harmony-rich that gently spirals into the void, instilling confidence at cruising speed before ratcheting into a heavier gear. Thick, tightly-sprung, heavy grooves propel this long-term expedition, jamming toward a new frontier. Tonight, the launch site is located at Boot & Saddle, where a pair of freshly sprouted local outfits in Cherry and Comb will join the ride, while the joy-inspired, self-described “baby punk” of Boston trio Free Pizza is certain to shake off those workday blues, releasing the tension in an exuberantly loose flourish. Boot & Saddle, 1131 S. Broad St., 7:30pm, $10, 21+ – Michael Colavita
