On March 27, 2009, Umphrey’s McGee performed at The Pageant in St. Louis, showcasing a dynamic live rendition of their song "1348." At this point in their career, the band had recently released their album "Mantis" in 2009, which featured a more progressive sound compared to earlier works. "Mantis" was notable for being the band's first studio album to be released through a crowdfunding initiative, reflecting their strong connection with their fan base. This period marked a significant evolution in their approach to music production and fan interaction. Interestingly, the performance also demonstrates the band's improvisational prowess, which is a hallmark of their live shows. The concert was part of a broader tour promoting their new material, further establishing Umphrey's McGee as a key player in the jam band scene during the late 2000s.
