Eight Gigs: Ostrich Theory

Fri., May 8, 8 p.m., Back 9 Sports Bar & Grill, $10

Elk Grove quartet Ostrich Theory plays a heady mix of music that truly defies categorization. The sampler on its ReverbNation webpage shows a band capable of playing different styles with dynamics not heard in Sacramento's indie music scene. The band is led by vocalist-guitarist Luke Martin and held together by the rock solid rhythm section of bassist Mike Stewart, drummer Jarrett Aitkens and keyboardist Robert Achilles. Fans of smart, angular alternative rock à la the Police and soaring melodies should check out “Tool (Human)” as well as the slower tempo of “Pilgrim.” Also on the bill are Frack Girls Burlesque and the CJ Davis Band. 7925 Arcadia Drive in Citrus Heights, www.facebook.com/OstrichTheory.
