In early 2011, Casey Meehan, founder of free online music distributor Rock Proper, started compiling weekly mixes featuring Chicago band and artists.

Shortly after, word of his Chicago-centric mixtapes go out, the local blogosphere was buzzing about the intriguing operation, which was soon dubbed Chicago Mixtape.

For the next year, Meehan would send a free downloadable mix offering the best in Chicago rock, pop and more to a rapidly increasing number of e-mail subscribers.

The project grew substantially in 2011, and Meehan and the Chicago Mixtape brand were even allowed to curate a charity festival for the Chicago chapter of the Neighborhood Boys and Girls Club -  an organization that provides scholarship programs for local adolescents and teens - this past summer called the Ultra-violet Petting Zoo. The event featured a number of up-and-coming Chicago acts including garage rock duo White Mystery and groovy blues outfit Bailiff.

One year later, and Chicago Mixtape is still going strong. Which is why this Saturday evening, Meehan has put together a one-year anniversary party at Subterranean in Chicago's Wicker Park neighborhood. The event is not only a celebration of the project's first birthday, but also a fundraiser to aid its increasing costs.

But of course, the main draw is still the music, and Meehan didn't disappoint as he's assembled an eclectic line-up for the show. Symphonic outfit The Damn Choir, dream-pop duo Architecture, roots rockers The Shams Band and the Americana-influenced pop stylings of Elephant Gun are all set to rock out in support of Chicago Mixtape.

The music kicks off at 8:30 p.m. on Saturday, February 11. Tickets for the 21+ event are available now at Subt.net.
