In August 1975, during the Grateful Dead's performance at the Great American Music Hall, the band was in a transitional phase following a hiatus that lasted from 1974 to 1976. The concert featured “Big River,” a song from their 1973 album *Wake of the Flood*, which was their first studio album released after joining the Grateful Dead Records label. The choice to perform at this intimate venue reflected the band's desire to reconnect with their core fan base after an absence and coincided with the release of *One From The Vault*, a live recording that would later encapsulate the essence of that performance. This recording is particularly notable as it showcases the band's unique blend of rock, folk, and improvisational jams, emphasizing their evolving musical artistry. The Grateful Dead's live shows were known for their dynamic setlists and extensive improvisation, which kept fans coming back for memorable concert experiences.
