The brainchild of Don Cowie, this festival’s been going on since 2006.┬áIt started at the Exchange, and this year is being held at Artesian on 13th. I don’t know if it has a firm mission statement. But if you visit the website www.cowrocks.com you’ll learn that the festival typically involves local musicians joining forces with each other in different combinations to perform a mix of original and cover tunes.

MC’d by Richie Wade-Cummings, the 2011 festival features two slates of performers: from 8-9:30 p.m. Wolf Hall, Down Beat, Sarah Schill, Shane Reoch and The Backhomes will play. Then from 9:30-11 p.m. it’s Brittany Soriano, Tahnis Cunningham/Ray Bell, Spout/Bec and The Underground Collective.

Tickets are $10 at the door.
