Thirty years into a career built on challenging convention, Garbage arrive at London’s Roundhouse looking anything but content to trade on nostalgia. Despite three decades of touring the capital, tonight marks the band’s first appearance at the iconic Camden venue, and from the moment Shirley Manson, Duke Erikson, Steve Marker, Butch Vig and touring bassist Nicole Fiorentino step onto the stage, they perform with the urgency of a band still determined to push forwards rather than look back.
