These guys can be found making appearances at hotels on the Varadero peninsula. They are great and a joy to experience!
The band members may change from time to time (for example: one day there was a female singer, the following day had a male singer).
They appreciate tips when finished their set, but an even better value is to just purchase one of their CDs. Then you get to take the music home with you!
I bought the "Mi son entero" CD and it does not disappoint. It's a mix of familiar Latin cover songs.
Here is some info listed on the back of the CD if you're interested in tracking them down:
