A killer one-two combo punch over at Mao Livehouse as two powerhouse indie acts take the stage. Shanghai dance punk renegades Absolute Purity, who struck gold two years back with their debut - a blissed-out mix of post-punk, electronica, and psychedelic music that is packed to the gills with surprises - have only gotten better since. Led by swelling synths, driving bass, pummeling drums, and the taut yet delicate vocals of Wen Jun (formerly of Guai Li) which vibrates from desperation to innocence with crackling ferociousness, the band recalls everyone from My Bloody Valentine to Health - yet stands on its own ground. Meanwhile. longstanding Beijing indie rock outfit Glow Curve, known for their evocative mix of atmospheric post-rock theatrics and grungy indie rock gravitas finds solace in the industrial dissonance of their sonic world and the futuristic electronically-enhanced looping rhythms.
