Wednesday's rock and roll show at Flicker is brought to you by the letter M and features two noteworthy bands from the marvelous music mecca of Austin, TX. The first, a four-piece called Milezo, released a very good record called Pathways at the tail end of 2013. The album owes much to some of our most beloved local sounds—namely the sunny, lysergic pop of Elephant 6—but also takes cues from windows-down psych-gaze groups like the Brian Jonestown Massacre. The second, Marmalakes, is a leaner and cleaner folk-rock group with an affinity for diamond-edged song structure and sweet, soaring melodies. On-again locals Mouser fall somewhere in the middle, pop perfection hidden beneath spazzy squall.
