Billed as the "World's Largest Music Festival," Milwaukee's Summerfest has announced its massive 2014 lineup.

Spread over 11 days, Summerfest features daily headliners (who play inside the Marcus Amphitheater) along with a multitude of other acts who will make up the festival's myriad stages from June 25 to July 6, with a day off on June 30.

So far, eight amphitheater headliners have been named: Bruno Mars, Lady Gaga, Brad Paisley (along with Darius Rucker and Joel Crouse), Outkast (along with Gark Clark, Jr.), Dave Matthews Band, Zac Brown Band, Motley Crue (with Alice Cooper) and a Fall Out Boy/Paramore co-headlining bill. Tickets to the amphitheater shows are sold separately from general admission passes. All tickets are available here.

Outside of the main stage, there are still plenty of acts to look forward to, covering virtually every genre fans of current music could hope for. There is contemporary country (Kip Moore, David Nail), hip-hop (Nas, Ludacris), punk (Joan Jett, Rise Against), indie rock (Brand New, The Hold Steady), indie pop (Tegan & Sara, Best Coast), popular metal (Five Finger Death Punch), EDM (Robert DeLong, Girl Talk, DJ Pauly D), legitimately legendary dance music (New Order) and even a cappella (Pentatonix).

The lineup was revealed today throughout southeastern Wisconsin via 43 outdoor billboards, though the lineup can also be sampled in the video below and viewed here.
