Indie Orchestra benefiting HAAM w/ Unwound Sound, A Giant Dog, Caleb De Casper, Daniel Fears, promqueen, Thor & Friends [Austin Media Center]

A kind of centrifuge, Brent Baldwin’s Indie Orchestra (I/O) has transformed the songs of Austin artists across genres with a glorious whirlwind of orchestral and choral arrangements since 2014. This year’s installment, benefiting HAAM, brings Sabrina Ellis back to the stage, now taking a Bite with A Giant Dog. Caleb De Casper’s dramatic dance floor electro-glam demands orchestral backing, as does promqueen’s provocative mix of breathless rap and beat-heavy pop. Daniel Fears’ subtly smooth R&B readies for reinvention, while Thor & Friends offer up their experimental percussion to the cause. – Doug Freeman
