Multiple headliners have already been announced for Summerfest's big 2018 event.
The 11-day music event, dubbed the "world's largest music festival," will see performances by Journey & Def Leppard, Dave Matthews Band, Florida Georgia Line, Halsey & Logic, and James Taylor & Bonnie Raitt.
Journey & Def Leppard will headline the big Fourth of July celebration at the festival as they team up for a massive co-headlined North American tour, which will also be coming to Chicago's Wrigley Field.
Tickets for the show go on sale Feb. 3, one day after Dave Matthews Band tickets are listed.
Tickets for James Taylor & Bonnie Raitt and Halsey & Logic go on sale Friday beginning at 10 a.m. and noon, respectively.
Florida Georgia Line performances go on sale Saturday.
The already announced acts will perform at the American Family Insurance Amphitheater, though organizers have yet to announce which acts will take the stage for several other dates.
Lineups for ground stages are expected to be announced in the spring as well.
This year's festival in Milwaukee will take place June 27 to July 1 and July 3-8.
