Jenny Lewis dropped LSD just once, and she doesn’t plan on doing it again. But the former Rilo Kiley frontwoman devoted this song to her one odd and scary trip. "I found the psychedelic experience to be totally terrifying,” she said. "I don't need psychedelics. I've lived a good and strange life.” Recorded live with her acoustic guitar and an all-male chorus, "Acid Tongue" is a stripped-down country tune with the warmth of a gospel choir — a fitting complement to Lewis’ sultry voice.
