Who said the corporate world couldn’t rock? Back for its 15th year, the Health Alliance for Austin Musicians’ (HAAM) Battle of the Bands gives stage and spotlight to professional bands who don’t get nearly enough opportunities to shout, shout, let it all out. Each act – sponsored by a local business – has 12 minutes to show what they can do and impress a panel of celebrity and industry judges for the chance to add one of the coveted superlatives to their names. Past winners include Phil Spectrum and the Pantones, the Haptics, the Mag Stripes, and last year’s Band of the Year, Noella Grey and the Imaginary Band. To date, the event has raised nearly $2 million in aid. – Cy White
