Weekend Agenda: Underground Music, Urban Assault Ride

A hot new club, a slew of indie rockers and comedian Dave Foley are all part of this weekend's social scape in the Mile High. Tighten your seatbelts, Denverites.

The UMS: Indie fans, call in sick, buy your passes, and spend the next four days in indie heaven, as 300-plus local and national artists descend upon 25 venues throughout South Broadway for the 11th annual Underground Music Showcase.

Chloe Grand Opening: Welcome LoDo's newest venue -- Chloe Discotheque -- in sleek, jet-setting fashion. Open bar, gourmet treats and free valet are just a few of the ways this newest Lotus Club member is celebrating her arrival.
