A hefty offering of emotionally fraught core music and symphonic metal over at Cave as two of Shanghai’s most renowned and distinctive metal acts join forces. Hoping to ‘unlock the knot in your heart and help you move through the turbid current,’ Return to Sender band taps into both the muscular and tender aspects of core music with whiplash-inducing flair, injecting their sound with shades of post-rock, R&B, emo pop, and then some. Meanwhile, Urizen Society fuses black metal and symphonic metal that’s grand as can be - offering soliloquies before breaking out into a blood-curdling scream - all while decked out in elaborate theatrical costumes.
