Sing Sing

A modification on karaoke chaos, Sing Sing is a dueling-piano bar where audience interaction is encouraged and bawdy jokes accompany the familiar songs. Crowd members try to stump the mind-bendingly knowledgeable pianists, and they often fail. While this concept can be cringe-inducing, the whole process makes more sense the more one drinks -- not an inexpensive prospect in this LoDo landmark.
