Foals made it all but impossible to stand still during a caffeinated set that crossed new-wave tunefulness and sharp bursts of post-punk noise. In persuading the crowd to clap and jump in unison with the music, the Oxford quintet led by example. Vocalist Yannis Philipakkis marched in place during verses and convulsed into a blur of elbows and knees when he got the chance. Perhaps most importantly, the quintet realized the quickest way to fans' hearts: free water. They tossed out bottles of the clear stuff when they weren't busy locking into the hypnotic "Cassius," pogoing through "Hummer" or flirting with math-rock on "Two Steps Twice."
