Berlin, summer 2012, Deezer organized a hackathon for celebrating the launch of their API. Max pitched the idea of making a concert recommendation app while listening to the music thanks to Deezer. After building teams, some fancy development during a week-end long, we won the hackathon, which allowed us to keep on working more over it, but we did not go much further of having a prototype. But feel free to use it as a musicplayer!
