Tipping their hats -- and beers -- to the club, the Davenport Collective is holding a two-day benefit for Pat's, with proceeds going to buy better P.A. gear. Boasting a handful of Cleveland's most compelling bands, the collective now spans some 15 groups. Many of them will be on hand this weekend, including the blissed-out, feel-good rockers of the Volta Sound, the snarky blues spitfires of the New Lou Reeds, and the mesmeric, folk-leaning Dreadful Yawns. Finally, getting drunk and rocking out will result in something a little more edifying than a hangover.
