J.R. was very professional. Exceptional and super nice to work with. He had the crowd moving at all times and into the music. He stuck to the playlist that our daughter and son-in-law provided. Even when the wind blew the tent over that WE had set up he never missed a word when talking and playing the next song. He kept rolling along, just like the wind. It was awesome. Highly recommended to use at any event. Thank you again J.R.
