East Nashville is seeing some great arts emerge also. This weekend we actually had the Tomato Arts Festival near the Garage Mahal (art gallery). The area has an active gay residential area. Many of the neighborhoods were pioneered by the LGBT community. Popular "Lipstick Lounge" is the gay hotspot in the east with Mad Donna's opening across the street soon.
V_harrell is correct, the gay area is Church Street and includes bars Tribe, Play, Blu, Lucky's Garage; restaurants Red and Chappy's; retail Joe's, Outloud! and the new OutCentral gay resource center (opening soon). Art-wise, there are little (if any) few art outlets in that immediate area. The downtown arts district / art avenue would be the closest there.
