Last month, Summerfest 50 – with the help of "Jimmy Kimmel Live" – dropped almost its entire list of grounds stage headliners. The key word there is "almost," because while it was a massive flood of famous names, there were still a few holes and TBAs left to be filled out.

Good news (unless you're a Brett Eldredge fan): Today, those vacancies are no more, as Summerfest announced the rest of its grounds stage headliners, including Ludacris, Maze featuring Frankie Beverly, The Spinners and Lee Brice – replacing fellow country star Brett Eldredge, who had to bow out of the Big Gig due to a scheduling conflict.

Here is a complete list of the new headliners and nationally recognized supporting acts added this morning:
