Foursquare today announced the creation of "specials" for concerts, a new feature that will allow artists to create promotional pushes, give away prizes, and offer exclusive rewards for fans who check into their concerts using the service.
For artists, this can range from seat upgrades, merchandise giveaways, meet and greets, special encores, and anything in between, helping to further enhance artist-fan interaction connections through social media. And the location-tagging company is planning to launch the new function at the very place it debuted in 2009 -- SXSW -- where they have linked up with a number of high-profile artists to take advantage of the festival where check ins and social media are equally ubiquitous.
Foursquare has more than a dozen partners participating in the launch, with specials that include Gary Clark, Jr. and current Billboard cover stars fun.  offering special encores if enough fans check in to their shows, signed posters of the Counting Crows for anyone who checks in to their BMI Auditorium Shores show March 16, signed EPs for those checking in to see Gold Fields and Morning Parade, free downloads from both Walk The Moon and Dry The River at each of their performances, free poster giveaways from Oberhofer and Daughter, meet and greets for those checking in to shows by Asher Roth, Chris Cab and Neon Trees, and drink specials and Skull Candy headphones for those checking in to either of The Warner Sound's two showcases March 14 and 15, to name a few.
The company has also created a simple tool  for any artist who wants to run their own specials while playing shows or out on tour, making it easy to give fans even more incentive to get out and see live music.
Foursquare first ventured into the music realm in August with their partnership with Songkick, which allowed users to check in to actual concerts and events rather than just the venues that housed them, adding a new dimension to the app's social sharing capabilities.
