On June 10, 2013, HAIM performed "Forever" on the Late Show with David Letterman, marking a significant moment in their rise to prominence. At this point in their career, HAIM was just gaining traction in the music scene after the release of their highly acclaimed debut EP, "Forever," in early 2013, which featured the title track they performed on the show. This performance helped to elevate their profile, showcasing their distinct blend of pop, rock, and R&B influences. The publicity from the Letterman appearance contributed to the growing anticipation for their first full-length album, "Days Are Gone," which would be released later that year in September. Additionally, HAIM is known not only for their musical talent but also for their strong familial bond, being composed of three sisters, which adds a unique dynamic to their performances and songwriting.
