Like fellow main stage draws deadmau5 and Hardwell, 22-year-old Porter Robinson has been critical of the EDM revolution since he himself transformed the scene with his frantic, genre-blurring “complextro” soundscapes back in 2012. Unlike his contemporaries in criticism, Robinson has made a calculated shift away from his former career-defining sounds. His debut LP, Worlds, pivots toward the tender electronic layers of talents like M83 and Passion Pit. A step forward for his career? Depends if you measure success by Facebook “Likes”, iTunes downloads, and guarantees, or by earnest artistic development.
