This year's Lollapalooza is more stuffed than a Thanksgiving turkey. With the festival landing in Chicago on Friday (Aug. 3), Billboard has your guide to the weekend's must-see bands.
Michael Kiwanuka | 1:30 p.m. | Playstation Stage
Why He's Hot: The U.K. singer's "Home Again" finally landed on shelves this week, months after his debut U.S. dates drew universal acclaim for his mellow brand of vintage soul. To borrow a phrase from Jay-Z, Kiwanuka's like a young Marvin in his hey -- don't let his early slot keep you from catching him.
Totally Enormous Extinct Dinosaurs | 2 p.m. | Perry's Stage
Why They're Hot: The project of U.K. producer Orlando Higginbottom offered a chilled-out EDM sound with debut full-length "Trouble," but the musician's exuberant remixes show he knows how to ramp things up into dancefloor-ready BPMs for a festival crowd.
Sharon Van Etten | 3 p.m. | Google Play Stage
Why She's Hot: With this year's "Tramp," the indie singer has proven herself a compelling heir to the likes of Cat Power and Tori Amos.
Black Sabbath | 8:05 p.m. | Bud Light Stage
Why They're Hot: It's Black Sabbath, even without drummer Bill Ward. This is as metal as it gets -- you can see the Black Keys next year.
tUnE-yArDs with Washed Out | 10 p.m. | House of Blues
Why They're Hot: The indie heavyweights -- one a frenetic experimental pop act, the other the leader of synth-subgenre chillwave -- get hot and cold at the House of Blues.
Passion Pit with GIVERS, Kishi Bashi | 8 p.m. | House of Blues
Why They're Hot: If Black Sabbath's not your style, step into the House of Blues for an electro-tinged set from Billboard 200 top 10 newcomers Passion Pit, whose pop-packed "Gossamer" just bowed at No. 4.
Chief Keef | 12:15 p.m. | Perry's
Why He's Hot: Look for the teenager rap phenom to draw a hometown crowd for his lunchtime set, which comes on the heels of breakthrough single "I Don't Like," a song that's scored over 2 million YouTube views.
FIDLAR | 1 p.m. | Google Play Stage
Why They're Hot: Los Angeles punks FIDLAR -- short for "F*** It Dog Life's a Risk" -- have made waves with their "DIYDUI" EP, a set shot through with a slacker enthusiasm that should bring a SoCal breeze to the 90-degree Chicago heat.
Alabama Shakes | 4:15 p.m. | Bud Light Stage
Why They're Hot: The blues revivalists' live shows are already legendary, incendiary spectacles, powered by the bottomless voice of Brittany Howard. Expect to hear them from here to the parking lot.
fun. | 4:45 p.m. | Google Play Stage
Why They're Hot: As the Alabama Shakes wrap it up, sneak out in time to catch fun. (or is it FUN.?) lead the crowd in an epic rendition of "We Are Young," a sing-a-long hit that's kept the band in the Hot 100 for 31 weeks and counting.
Frank Ocean | 8:45 p.m. | Google Play Stage
Why He's Hot: If there's one man not to miss this weekend, it's Ocean, whose "Channel Orange" is one of the year's most original R&B efforts and whose brave declaration of a same-sex love affair has made him one of the most talked-about artists of 2012.
Calvin Harris with Nathan Scott | The Mid
Why They're Hot: If you want to keep dancing deep into the night, party with "We Found Love" producer Calvin Harris -- whose solo material should keep the floor bumping just fine even without Rihanna.
Jane's Addiction with Franz Ferdinand | 10 p.m. | Aragon Ballroom
Why They're Hot: It wouldn't be Lolla without a sweaty set from Jane's Addiction, who'll get a boost from the Scottish rock action of Franz Ferdinand.
Bowerbirds | 12 p.m. | Sony Stage
Why They're Hot: The folk group weathered a break-up -- the emotional kind -- before getting back together for their strongest album yet with this year's "The Clearing." Bowerbirds should be a lush, gentle way to ease into Lolla's final hours.
The Walkmen | 3 p.m. | Sony Stage
Why They're Hot: The indie mainstays remain New York's finest -- new album "Heaven" captures the once-dour group at their happiest, and most tuneful, yet.
Yuna | 5:40 p.m. | BMI Stage
Why She's Hot: The Malaysian singer-songwriter made her U.S. launch with help from Pharrell Williams, who produced recent single "Live Your Life." Her melodic, affecting songs are mysterious without losing accessibility, leading her self-titled U.S. debut to a No. 23 spot on the Hotseekers chart.
At The Drive-In | 6 p.m. | Red Bull Soundstage
Why They're Hot: The reunited rockers represent a sound that's been largely absent from the music world in recent years: the band plays with both the visceral power of hardcore and the thoughtfulness and range of indie. See them while they last.
Jack White | 8:15 p.m. | Redbull Soundstage
Why He's Hot: On a big day for rock, Jack White himself should close the festival in style -- likely with two different bands playing material from his solo debut. If the house hasn't been brought down yet, look for White's hand on the wrecking ball.
Billboard Post Party: Of Monsters and Men with the Jezabels | 10 p.m. | The Double Door
Why They're Hot: Don't miss Billboard's own Lolla bash, featuring Icelandic alternative stars Of Monsters and Men and Aussie favorites the Jezabels. A special DJ set from Brooklyn's French Horn Rebellion will round out the evening, which will be emceed by The Beat host Jonathan Brooks.
