Founded in 2001 by journalists John Moore and Ricardo Baca of The Denver Post, the Underground Music Showcase was originally conceived as a humble, one-day, locals-only concert highlighting the diverse music scene in Denver. Today, the UMS is Denver's largest and longest-running music festival, drawing more than 10,000 music lovers to the South Broadway music district for three days every July. UMS has featured generations of artists and bands from Colorado, including some of the state's best-known acts.
