Florida Georgia Line/Nelly/Chris Lane

Since breaking out in 2012 with the smash hit “Cruise,” the country act Florida Georgia Line has received all kinds of awards and previous releases, Here’s to the Good Times and Anything Goes, have gone platinum. The soulful piano ballad “H.O.L.Y.,” the lead single form the band’s latest album, last year's Dig Your Roots, topped the Billboard Hot Country Songs chart for 17 weeks upon its release, turning the album into another major hit for the duo. And yes, you read that right, rapper Nelly joins the group on tonight's bill. The connection? Florida Georgia Line had a cameo on his latest album. (Jeff Niesel)
