Canadian noise-pop duo PS I Love You got its start when singer-songwriter Paul Saulnier decided the guitar, organ and Casio keyboard he was using to make music weren’t enough. So he dumped the percussive sounds of the Casio, opting for Benjamin Nelson as a drummer. Their debut album, the lo-fi Meet Me at the Muster Station, came out in 2010. And now PS I Love You (above, doing “Facelove” for KEXP FM) is back with a second LP, Death Dreams. See them play Mercury Lounge tomorrow night.
