Without dueling pianos, crowds could only determine a musician's aptitude through televised talent shows and oboe-hurling contests. Experience a clean, nonviolent night out with today's Groupon: for $29, you get a reserved table and group admission for four—including $15 worth of drinks—at The Big Bang, a dueling piano bar in Tempe (up to an $89 total value).

After the doors swing open, The Big Bang regales guests with an evening of food, drink, and rambunctious, piano-fueled singalongs with their crooning cronies. From the acoustic confines of a reserved table (up to a $50 value during peak hours on Thursday, Friday, and Saturday nights), you and your impromptu barbershop quartet (cover for four is a $24 value) can warm up your vocal chords with a round of drinks.

Once you've consumed the regulation amount of food and drinks, take your lilting falsetto or river-dredging baritone to the stage, where a rotating handful of multitalented melody makers lead feuding teams of beer-fueled patrons in singing or yodeling their favorite bar tunes. Dramatic ivory-fueled combat is further supplemented by vibrating bass, explosive drums, laser-guided keytars, and other musical weaponry. They'll take any request you like, with a repertoire spanning from rollicking rock classics to modern hip-hop and R&B noisemakers. An energetic, round-the-clock live show encourages hip shaking and feet shuffling until 2 a.m.
