If your Spotify recommendations have had you doing double takes lately, it’s with good reason: A spate of musicians have, of late, adopted groan-worthy pun homages as their stage names. The culprits range from Penn-educated rapper Hoodie Allen (né Steven Markowitz) to stoner-happy psych guy Salvia Plath (Michael Collins), lo-fi bedroom act Elvis Depressedly (Mat Cothran), Welsh noise-pop band Joanna Gruesome, and Australian electro-soul producer Chet Faker (Nick Murphy). Faker, who released the excellent Built on Glass (Future Classic/Downtown) in April, is headlining a North American tour this fall, starting August 23 and continuing through October.
