If you are in the market for a really good latin jazz ensamble that does a huge range of songs in several languages the Karen Rodriguez is the way to go. Her band is as professional as it gets and never disappoints a crowd. They can play to suit any event. See her site for bookings and samples.
Here are a few recordings I have done while doing sound for her band.
