JAMM is a band that appeals to the masses. No matter what your age, background, ethnicity, or music preference is, they have a set list that rivals that of a wedding band. Expect a mix of everything from the 50s to today. I enjoy them because they are upbeat and act completely professional. You can tell this group has been around for awhile, by the spot on performances and how they easily transition from an upbeat modern song to a slow, relaxing cool 70s ballad. Their female vocalist can belt out a wide range, and isn't scared to show it off, either. I have seen this band play a lot of Chicago, Earth, Wind & Fire, Michael Jackson, Beyonce, and even Frank Sinatra. Here is a youtube video of JAMM with their frontman, Jonathan Potenciano, singing Frank Sinantra's The Way You Tonight.
HINT: JAMM is a band that has a facebook fan page. Check out Bally's or JAMM's page on Facebook the week you are in Vegas to see when/where they are performing. Then, go to Bally's and grab a late night snack at the Tequilla Bar (open til 6 am!) for $10 and enjoy the show!
