The 29-year-old Swedish pop singer-songwriter Tove Lo personalizes her huge, neon hooks with lyrics that detail her internal struggles and bad habits, offering catchy screenshots of life in the sex, drugs, and EDM age. This idiosyncratic musical identity has been Lo’s signature ever since her 2013 breakthrough single, the No. 3 hit “Habits (Stay High).” Fast forward to last year and her sophomore album, Lady Wood. Though neither of its singles (“Cool Girl” and “True Disaster”) received as much attention as “Habits,” Lo’s star has continued to rise, and she’s become a sought-after festival performer — later this year, she’ll play Coachella, Bonnaroo, Governors Ball, and Lollapalooza’s Brazil, Argentina, and Chile fests.
