The latest startup looking to help music artists sell live recordings to fans is Soundhalo, which launched yesterday. Initially available as an Android app and website, the service will sell official live audio and video recordings, with fans able to buy and download while a concert is in progress. Social features are also built in, with fans able to share recordings with friends and comment on what they’re watching or listening to. Alt-J are the first band to take advantage, selling recordings of their Brixton Academy gigs this week through Soundhalo. Fans can buy entire sets or individual tracks, with video and audio recordings included in DRM-free file formats. “For the first time in history you can now download the song that you are actually listening to, straight from the stage into the hands of the fans, in real time,” says CEO Liza Boston. Soundhalo’s success, though, depends on which artists it signs up, and how well the service is promoted at their gigs and beyond.
