An indie pop duo whose music has a cool retro vibe buoyed by smooth melodies, a naturalistic sound, and warm harmonies, Purr is a collaboration between songwriters, musicians, and longtime friends Eliza Barry Callahan and Jack Staffen. The two previously worked together as Jack + Eliza, but while that project emphasized spare and stripped-down accompaniment, Purr's recordings feature a fuller sound with a larger palette of instrumental flavors that often reference 1960s pop. Purr introduced themselves to the world with a 2018 single, "Bad Advice" b/w "Painted Memory," that showed off their talents as both writers and vocalists, and they further refined their style on their first full-length album, 2020's Like New. 2023's Who Is Afraid of Blue? saw the pair expanding their sound with electronic flourishes and more expansive arrangements.
