On July 3, 2015, Umphrey's McGee performed "Shine On You Crazy Diamond" at the iconic Red Rocks Amphitheater, a venue renowned for its breathtaking acoustics and scenic backdrop. This performance came shortly after the release of their album "Forget Not," which was a collection of unreleased tracks and was made available in 2015 to celebrate the band's 20th anniversary. The band's distinctive style of blending rock, jazz, and funk, as well as their commitment to live improvisation, are hallmarks that continued to evolve during this period. At this time in their career, they were also known for their dynamic live shows and deep connection with their fan base, often using technology to enhance live recordings and interactions, as highlighted by the professional filming efforts of TourGigs for this performance. This mix of careful production and improvisation reflects the core of Umphrey's McGee's musical ethos.
