Book them. Right now.
I don't know how I can say much that hasn't been said about them in other reviews, but they were incredible. My husband and I went to a number of weddings out-of-state just before ours, and the bands really made (or rath...er, broke) most of those weddings. KTG not only sounded absolutely incredible, they also nailed the things other bands miss. First of all, they played awesome music that people of all generations loved. Our dance floor was packed with ages ranging from 20-somethings to 70-somethings from their very first song all the way until the end of the night. Something we learned was important from another wedding: the transition time between songs is key (at the other wedding, their band lagged by a good 5-10 seconds between songs and the dance floor would be empty by the end of that time); with KTG there was no "lag" time, it was a seamless, non-stop dance party. They also only took one break during our dance party, and it was no more than 10-15 minutes. To quote my friend and fellow wedding critique "they just brought down the house. They need a minute." After they came back out, the party was back all the way until the end of the night.
I would recommend them simply for how incredible they were as a band, but I also have to rave about how wonderful the band manager/contact, Kenny, was. He was the fastest response time out of all my vendors and was also so incredibly accommodating . We had some very particular special requests for our wedding and each was executed perfectly. Those being well-executed really turned the unique aspects of our wedding into highlights of our night.
I can't express my gratitude enough. These guys were worth every penny. They made the night.
