Atlanta's annual festival, Music Midtown, is expanding into a two-day event, which will take place 9/17-18 in Piedmont Park. The just-announced headliners are The Killers, twenty one pilots, Beck and Deadmau5, and performers include Alabama Shakes, G-Eazy, ColleGrove (Lil Wayne and 2 Chainz), The Lumineers, Kesha, James Bay and more. See the full lineup below.

Tix go on sale Friday (6/24) at 10am EST via the fest's official site and Live Nation. However, a presale for Citi cardmembers started today, and will go on through Thursday at 10pm EST via the Citi Private Pass Program.

The HITS Private Pass Program, meanwhile, can get you an inside look at a bunch of stuff you really don't wanna look at. Stay tuned, as we prepare to launch that—and by "stay tuned" we mean "run for the hills."
