During a recent conversation, Seth Rogen and Kathryn Hahn reminisced about attending a Grateful Dead show together. Rogen humorously reflected on taking acid before the show and being blown away by the experience. Hahn agreed, noting that she danced the entire time despite not knowing any of the music.
Rogen admitted that he didn’t know any of the band’s songs before the show, but after hearing them live, he declared them his favorite band of all time. The connection between acid (LSD) and the Grateful Dead is well-known, as the band participated in Bay Area acid test experimentation parties in the 1960s. These parties led to improvised concerts and even saw the band members indulging in psychedelics themselves.
