Record release day for Purity Ring will find them in downtown Manhattan, displaying their lights and beats in the round enclosed by a surely packed room. Shrines, the warped Cronenberg-creepy synth pop record debuting on 4AD today, will demand the crowd. And since tracks like single “Fineshrine” have singer Megan James begging, “Get a little closer, let fold/ Cut open my sternum and pull,” a bit of over-intense closeness is only proper.
