Mac Miller hit up Carnegie Mellon University in Pittsburgh to headline their 2014 Spring Carnival last night (Apr. 11). Performing in his hometown, Mac made a special announcement to the audience that his next mixtape would drop on Mother's Day (May 11). Adding to the occasion, he let fans in on three previously unreleased tracks. While he never dropped a name for the first song, he did share the names of the other two: "Therapy" and "Insomniac." No word on those four albums that he's been working on, however.

Watch Mac Miller debut the new tracks in the videos below:
