By October 13, 1968, when The Beach Boys performed "Good Vibrations" on *The Ed Sullivan Show*, the group was transitioning in their career. Their previous album, *Friends*, released in 1968, showcased a softer, more introspective sound, moving away from their earlier surf rock roots. The performance on Ed Sullivan highlighted a mix of their classic sound and the evolving musical landscape of the late 1960s. This particular live recording is significant as "Good Vibrations" was not only a major hit for the band, but it was also one of the most innovative songs of its time, known for its complex structure and use of unusual instruments like the theremin. The performance on such a pivotal television show reflects the band’s enduring popularity and influence during this era, even as they were navigating the shifting tides of the music industry and their own artistic directions.
