If Carpool’s 2020 record Erotic Nightmare Summer was a band finding their footing and firmly establishing themselves on solid ground, the group’s new EP For Nasal Use Only finds them fully exploring the landscape they’ve created, searching for every sound and idea to throw in and pushing the boundaries of what you’d expect from the group. Carpool still plays in a wild manner, with more sick riffs and drum fills to count, but they’ve added synths here and leaned more into sunny pop vibes, reflecting the lyrics that pick up the self-destructive behavior documented on ENS and take the logical—if difficult—next step of trying to change and lead a more sober, clearheaded life.
