The Underground is one of Reno's largest music venues and cannot be classified easily. Shows here range from all-ages top 40 parties, national, regional and local artist concerts, post-Burning Man parties where anything could happen and private events. The bar is open for those 21+. The music style varies wildly depending on the night, with shows ranging from hardcore to world beat, just about any other genre you can think of or just a big party with DJs. The space has a nice, converted urban feel with brick walls and more space than any most other venues' stages.
   
The Tree House Lounge's walls are covered in art, a stage (complete with stripper poles), and it hosts just about any type of event. The Tree House is located behind The Underground with an entrance at the rear of the building. The name draws partly from the architecture. Those who visited the room before the changes should be familiar with its jungle-gym feel. The Tree House is a 21-and-over place. Despite the proximity, the two venues keep separate counsel and host separate events with unique vibes.
