God bless Alexander. Not just because the Fort Lauderdale indie-rock group's charismatic frontman, Ryan Alexander, inserts his passionate religious beliefs and stances regarding poverty, politics, and the human condition into the lyrics. There's a dedication to songcraft here that can thread together neatly like Death Cab for Cutie on record but will turn around and chomp up the stage when they perform live. "Peter, James & John (Backward Math)" from new album The Other Side of Symmetry is a catchy statement, pure and simple, and while the usual trend for alt-leaning rock is navel-gazing, at least this band is trying to strike a positive balance between preaching and preening. Not yet a convert? Look to Alexander's many well-kempt disciples, who always arrive early and provide vigorous support for every electrifying chord — as well as when the guys seductively flop their shaggy hair. Getting a message across is sometimes just as simple as turning up the volume.
