Sardonic, effete, and proudly, conceptually commercial upon their ’80s arrival, Pet Shop Boys have since cemented themselves as world historically great pop artists. From the introductory Euro-rap of “West End Girls” through the emotional lushness of Behaviour and Very to their brand-new Electric, Neil Tennant and Chris Lowe have infused electropop with sui generis drama and humanity for three decades. And to make up for the dinkiness of their “band,” their stage shows are extravagant visual productions, this one created with designer Es Devlin and choreographer Lynne Page.
