FLO are at the center of a contemporary girl-group resurgence alongside peers such as Katseye and XO. And, pivotally, they sing about love and heartache with the experience and aplomb of a cool older sister doling out advice. The songs on their follow-up, Therapy at the Club, invite more emotionally ambiguous and nuanced romantic dynamics into the trio’s tight pop songwriting. If love is a battlefield on Therapy at the Club, female companionship is the armor. On slinky soul track “Therapy at the Club” and Christina Aguilera-inspired pop song “Remedied,” the club is a respite because of the women by their side: the friend who got their lonely ass out the door, the girl who started the night as a stranger and became an accomplice.
