The Festival Internacional de Benicàssim — universally known as FIB — is one of the longest-running and biggest indie-rock and electronic-music festivals in southern Europe, held every July on a purpose-built site at the edge of town. Past headliners include the Beastie Boys, Radiohead, Bob Dylan, Arctic Monkeys, Iggy Pop, Kasabian, Liam Gallagher, Florence and the Machine — the line-up reliably mixes major guitar acts with electronic, hip-hop and dance acts on multiple stages until dawn.
The crowd is heavily British, often described as "Glastonbury in the sun"; Spanish-speakers are a minority and the official languages of the festival are Spanish and English. Camping at the on-site campground is the standard accommodation; the festival roughly triples the town's population for the week. Tickets sell out months in advance.
