Dia de los Deftones is exactly what it sounds like: a festival curated by Deftones, the alt-metal titans with deep Southern California roots and an obsessive, genre-crossing fanbase. Held in San Diego at Petco Park around the turn of November, it pairs a Deftones headline set with a lineup that mirrors the band's own eclecticism, heavy and dream-pop, hip-hop and shoegaze, the sounds that live in the Venn diagram of their records. Part concert, part community gathering for a fandom that treats the band as scripture, it's become one of the most distinctive artist-curated festivals in the West.
