Worlds is the debut studio album by the American electronic music producer Porter Robinson, released on August 12, 2014, by Astralwerks. Initially known for his heavier bass-centric production, Robinson became increasingly dissatisfied with the electronic dance music (EDM) genre, believing it limited his artistic expression. In 2012, Robinson released his first song with a greater emphasis on melody, "Language", and decided thereafter to prioritize aesthetic and emotional qualities in his work.
