After a summer of much-praised high-profile festival performances, pop prog rockers Umphrey’s McGee heads indoors this fall to play in many of the country’s most beloved theatres. As always, along the way Umphrey’s continues to raise the bar for fan experiences, with their innovative and interactive Stew Art events planned in at least a few markets, and an incredibly creative first-time offer of “Enhanced Experience” fan packages for their always-epic Halloween Monster Mash-Up in St. Louis on October 30 and 31.
