Festival Collaborations: 5 Artists We'd Love To See Show Up At Lollapalooza

Lollapalooza is just around the corner (have you voted in our headliner poll yet?) and we're gearing up with sunscreen, rocker tees, cutoff jean shorts, and mud-proof sneakers. We're also practicing our psychic powers and trying to predict what surprises this huge rock festival has in store for us! Now don't get us wrong, the Lolla lineup seriously rocks but wouldn't it be fun to inject a little pop into the mix? Here are 5 acts we'd love to see come out on stage and surprise us:

Performer: Calvin Harris
Dream Guest: Rihanna
"We Found Love"

Calvin Harris played Coachella this year and his pal and superstar collaborator Rihanna showed up for a surprise performance. We know if we were at a show and unexpectedly saw Rihanna we'd lose it! "We Found Love" is sooooo fun to dance to.

Performer: The Weeknd
Dream Guest: Drake
"Crew Love"

This is Drake's song from his latest album Take Care and his fellow-Torontonian The Weeknd (aka Abel Tesfaye) is featured on it. We think that supporting his up-and-coming friend would be the ultimate act of crew love from Drake. Plus the crowd would go nuts.

Performer: Sigur Ros
Dream Guest: Shia LaBeouf
"Fjögur Píanó" (Video is NSFW!)

So Shia isn't exactly a musician but he did get naked in the video of some musicians, so close enough, right? We don't know if security would be too keen on Shia getting naked on stage though, so this collabo probably won't happen...

Performer: B.O.B.
Dream Guest: Taylor Swift
"Both Of Us"

We never expected these two to collaborate (ever!) but they did and it's actually kind of magical. We think even the hardest rockers have a little love for T. Swizzle hidden deep in their black-metal hearts so this surprise could go off really well.

Performer: Fun.
Dream Guest: Janelle Monae
"We Are Young"

This song was a strong contender in our Song of the Summer 2012 poll and has also been in our Top 5 lyrics for months now so it's clear that you guys love it. Fun. will no doubt be performing it with or without Janelle Monae but it would make it that much better to have her there on stage, wouldn't it?
