Savages rode the wave of buzz accompanying their first album into their U.S. TV debut yesterday, performing a pair of songs on Late Night With Jimmy Fallon. The London quartet ripped through "She Will," a dark and riveting tune marked by an icy guitar riff, thrumming bass and bursts of drums surrounding singer Jehnny Beth's explosive vocals. Afterward, the band stuck around for a web-only exclusive of "City's Full," a visceral song propelled by pummeling drums and jagged slashes of guitar. Both songs come from Silence Yourself, Savages' full-length debut.
