'Go Go Smear The Poison Ivy' marks a return to the playful experimentation of earlier releases. With the departure of Kristin Valtysdottir , the core of Mum is once again Gunnar and Orvar, but the band itself is larger than ever, counting in all seven people. Eschewing an otherworldly, almost magical aura, Mum make experimental music that is naturally, effortlessly imbued with a pop sensibility. Mum's new material bridges the gap between their universally acclaimed debut and their more expansive sonically detailed recent output. Sonically warm, gorgeously rich & melodic, the band use an array of instruments (guitar, bass, drums, synths, laptops, cello, accordion, mutated brass) alongside electronic bleeps,washes, and beats, blurring the distinction between live band and electronic outfit.
