Pet Shop Boys: Smash: The Singles 19852020 Parlophone 0190295021962 (6 LP). 2023. Various prods. and engs. plus Andy Baldwin, remastering eng. Performance ***** Sonics **** It's hardly news that pop can be simultaneously intelligent and fun, or that a music single can be both fun entertainment and a significant cultural artefact. Smash is evidence, as if any more were needed, that the Pet Shop Boys are sublimely good at that particular synthesis.
