Delta 5’s spiky feminist anthems loom over post-punk and riot grrrl. This vital set collects the politically defiant Leed band’s key singles, including 1979’s “Mind Your Own Business”, a mutant disco track shot through with hypnotically chanted slogans and guitars as pleasant as fingernails on chalkboard, and “Try”, nervy avant-funk showing off their love of sinewy basslines. You’ll also encounter a clutch of blistering live cuts: “Make Up”, recorded with radio host John Peel, is a blast of art-school R&B that slashes like razor blades.
