Unless you have been living under a rock at the bottom of the Mariana Trench, you’ve seen or at the very least heard tidbits of the Lollapalooza line up or its rapid ticket sales. If you’re now thinking “Lollapa-whaa?” go take a five-minute time out. Seriously, go. I’ll wait…

Now then, Lollapalooza, for the uninformed, is one of the largest music festivals in the United States and one of the “Big Three” along with Coachella and Bonnaroo. At this time, it’s still undecided which of them has the weirdest name, but that’s  another story.

Coming off of Lollapalooza 2011’s then-unheard of Electronic Dance Music (EDM) headliner Deadmau5 (Coachella and Bonnaroo 2011 had a combined zero EDM headliners), Lollapalooza has booked not one, but two headliners for you to shake your collective moneymakers to: Avicii, 22-year-old House DJ, and acclaimed French House duo Justice.

Lollapalooza’s EDM artists don’t end there. Perry’s Stage will once again return to Grant Park, a beacon of hope in the heart of every brostepper, I’m sure, with Bassnectar, Kaskade and Calvin Harris leading the party. As of now, it isn’t entirely known in what form Perry’s will return, but it sounds like it could possibly be ditching the tent for an even larger stage.

Rock fans, you can breathe a sigh of relief. While the EDM presence is strong at Lollapalooza, it has definitely been overshadowed by the sheer amount of rock power. From metal pioneers Black Sabbath to the White Stripes/Raconteurs/Dead Weather mastermind Jack White to funk rockers Red Hot Chili Peppers to bluesy duo The Black Keys, Lollapalooza creator Perry Farrell put it best when he commented that “this is one place where I can say the generation gap doesn’t exist.”

Now I could go on to talk about why it’s awesome that Sabbath’s only show in the US will be Lollapalooza, or how many awesome songs Jack White could potentially play thanks to his impressive catalogue of music, but I think we’ve all already got our own ideas about the headliners. Instead, if I may, I’d like to discuss the astoundingly impressive undercard of the Lolla line up and the different genre patterns that can be seen.

For those people who have been saying Lollapalooza is getting too electronic, all I have to say to you is, “What the folk?” The amount of folk music at Lollapalooza this year is staggering, with acts like The Tallest Man on Earth, Delta Spirit and Dawes, ensuring nobody forgets who Bob Dylan was for the entire weekend.

Also well-represented is music of the psychedelic variety, thanks to Neon Indian, The Black Angels and Tame Impala, all of which I cannot recommend enough.

It’s also worth noting the amount of Scandinavian indie rock that will be at Grant Park this summer. Of Monsters & Men (see review page 9) and Sigur Ros are reppin’ Iceland, while Miike Snow, First Aid Kit and The Tallest Man on Earth will be giving Lollapalooza goers a taste of Sweden.

Sadly, any festivalgoers expecting to hear some tasty jams are in for a disappointment, as Lolla failed to book its token jam act.

And while the lack of a hip-hop headliner has some dismayed, between Childish Gambino, rap collective Doomtree and J. Cole, rap and hip-hop are well represented. As for R&B fans, both The Weeknd and Frank Ocean promise to be excellent sets.

As for my own most anticipated act, well, let’s just say it’s gonna be a summer for the *wink wink* bronzed. (It’s Jack White.)

Lollapalooza has been selling tickets at a supersonic rate and within a week has sold out of its Three-Day Passes. One-Day Passes are still available…but for how long? *Cue Ominous Music*
