It was Kenny Chesney at Gillette the year that Hurricane Irene rolled in that the Zac Brown Band was one of the openers. Up until that point I wasn't the biggest fan... and then in the pouring rain they covered Sublime's 'Caress Me Down"... SOLD! That band can cover any genre of music! Their version of Metallica's "Enter Sandman"... AMAZEBALLS!!!
Well Zac Brown has a side project. A trio by the name Sir Rosevelt. It's def more poppy but it's so good! Check out their singler "Something Bout You"
