Summer's nearest mega-fest for Minnesota music lovers, Lollapalooza announced its 2015 lineup this morning with a pair of timeless giants, Paul McCartney and Metallica, and such recent breakouts Florence + the Machine, Sam Smith, Bassnectar, the Weeknd and Alt-J. The festival is once again scheduled in Chicago's Grant Park the first weekend of August, this year landing July 31-Aug. 2.

Of special note for Twin Cities fans are some of the acts who have yet to announce local dates on their current tour itineraries, since some of the Lolla performers often spill over and book a Minnesota concert in the days before or after their big Chicago gig. Some of the likely contenders in that case include Florence, TV on the Radio, the Weeknd, Gary Clark Jr., Tallest Man on Earth (playing Eaux Claires in June) and Flying Lotus. Metallica appears to be playing it as a one-off/fly-in sort of gig and doesn't have any other U.S. dates booked, but you never know.

Only one Minnesota act made the lineup this year, the one that was just on "Conan" last night: Hippo Campus (playing that Saturday). Several of the new buzz acts were a big part of the fray we covered at last week's South by Southwest Music Conference, for better (James Bay, BadBadNotGood) or worse (Stromae). The lineup announcement follows yesterday's reveal of the Outside Lands fest in San Francisco with Elton John, Mumford & Sons and the Black Keys.

Three-day general-admission passes for this year's fest sold out even before the lineup was announced. Single-day tickets go on sale today at 10 a.m. through the festival's site, where VIP passes are also available. Here's the day-by-day schedule:
