The First Sunday of every month will get you singing and tapping along with Retrograss, an incredible group of ever-changing musicians from around the Denver area.  This jam session is unique and exclusive to the Light Rail Art Gallery.  There are plenty of places to sit, adult beverages for sale, and an abundance of smiles to be had.  All ages are welcome, so come on down and sit a spell with the best musicians in the area!  What a great way to spend the afternoon!
