Setting a higher standard with each new release, Foals recent album Holy Fire was universally lauded and full of tracks that build to a tantalising crescendo of primal energy. Single My Number also debuted a poppier side of Yannis and co's musicality, claimed as Zane Lowe's Hottest Record in the World and later remixed by dance floor bandits Hot Chip. This Oxford-born quartet started life in the much talked about math-rock scene, classing Youthmovies and Battles as their contemporaries. After selling out the Royal Albert Hall in 15 minutes earlier this year, they return to Glastonbury for the third time as masters of epic-sounding, intensely orchestrated tracks that will knock your socks off when played live.
