For nearly 25 years, the Pet Shop Boys have been Euro-disco's poet laureates, setting epigrams worthy of Oscar Wilde to thumping Hi-NRG production. On their excellent 10th album, the music leans toward the ornate, with snatches of Tchaikovsky and spaghetti-Western atmospherics enveloping the synths and house beats. Neil Tennant and Chris Lowe are now past 50, and some songs take a surprisingly philosophical turn. But even romantic moments like "Love etc." are spiked with acid wit. "I believe that we can achieve/The love that we need," Tennant croons, adding, "You don't have to be beautiful/But it helps."
