The four-piece caravan of Really Fast Automobiles, a.k.a. RFA, cruises into the upstairs of World Café Live this evening. The band toes the threshold of easily assimilating garage rock with vocals that maintain an even keel, but appear on the verge of breaking loose from control and blues-inflected instrumentation that comes loaded with smooth riding rhythms and tight riffs. They’re crisp and clean like a good drink, but have the capacity to throw in another shot to stir things up. Clean contoured guitar licks and steady-handed, harmony-centric vocals shape The Reflexes‘ pop-rock sound, while the breezy warm crooning of Mike Bailer Band gets things started. World Café Live, 3025 Walnut St., 8pm, $8, All Ages – Michael Colavita
