Thrillcall has been in the concert listings game for a few years now with a site that’s similar to the likes of Songkick, Bandsintown, and JamBase. But today, they’ve announced a new mobile app that will offer a twist on the concert listings game — exclusive ticket offers via mobile to live music fans in LA and SF.

Sound familiar? That’s because we recently posted about a brand-new app called WillCall which just launched in the San Francisco area to offer concert fans last-minute tickets to shows. Both Justin and I got excited about that one, but it now looks like they’ve got some competition from one of the main concert listing providers.

Although similar sites like Songkick, Bandsintown, and JamBase have all had great mobile apps for some time, I don’t beleive any of them have specifically incorporated last-minute ticket deals into their mobile offering. Of course, there’s also that giant white elephant in the room — Live Nation / Ticketmaster — which recently partnered with Groupon to offer last-minute ticket deals for concert fans as well. Although the deal was not specific to mobile, one can certainly imagine it being a core part of their promo plan.

All of these developments point to interesting new era where promoters and ticketing companies are increasingly seeing mobile apps and social networks as hot channels for selling extra ticketing inventory. Although these apps remain largely untested, and we can only assume that most last-minute deals will not apply to the hottest tickets, it still makes for an exciting time to be an avid concert fanatic with a smartphone.

Now, if we can only get these apps in NYC!
