These guys were fantastic. Showed up early, played well beyond the scheduled time and were very accommodating. Many people at the party commented on what excellent musicians they were and how great their energy was. They sang happy birthday at our request, let us use the PA system during breaks, and invited some of the party guests to play with them at the end of the night. I was concerned that they might be too noisy and overwhelm the party, but volume was perfect. I'd highly recommend then- really a great experience all around.
