You might recognize him as the guy who sings the hook on Lupe Fiasco's "Superstar," but Matthew has certainly made his own mark on the music biz. While studying at Columbia College, both painting and music, he got in touch with Lupe. Between their partnership and the grassroots following he gathered playing Chicago coffee shops, he's now an internationally known musician. Check out our entire interview with Matthew on this Friday's "metromix" at 7, 8, and 9 p.m. For now, here he is performing "Days Like This" in Millenium Park...

Metromix.com and The Music Lounge hosted a Lollapalooza after party last night and we had to take part! The event was hosted at The Hard Rock Hotel and consisted of food, drinks, dancing, and much more.

Entering the party everyone was greeted by hair stylists and make up artists that were there to pamper all with a new look for the night. Jade dragon was also there hooking everyone up with complimentary ink of their choice! The dancing kicked off with a DJ spinning and then David Macklovitch of Chromeo showed up and took over the DJ booth.

Wanna know who else showed up?

Who's the most popular guy at Lolla? It's not Zack or Kanye. It's the guy giving away ice cream. Jackie tracked him down and got his story... and maybe a Bomb Pop.

Lolla favorite Gnarls Barkley guides the crowd into the last night of the festival.

Chicago loves it if your Irish... or if you play Irish punk music. The Lolla crowd gave Flogging Molly a warm welcome.

Love & Rockets: Reunited and it feels so good.

Lollapalooza founder Perry Farrell has a jam session with Rock God Slash. (Note: The audio isn't the best but the visual of these two legends performing together may be enough).

Chicago rapper Kid Sister perks up the crowd with her set on Sunday afternoon.

You know things are getting scary when Zack de la Rocha is the voice of moderation.

A gentleman next to me in the Rage Against the Machine crowd got this text message from a friend standing closer to the stage. And for the first time in my Lollapalooza-going experience, things got scary last night. There was a security breach, a few stops of the show, and more broken bones and busted noses than I've seen in a long time. Keep reading!

Just learned that no still photographers will be allowed in the front row pit during Kanye West's set tonight. Hmmm. Could this mean Barack Obama will be introducing him? We'll see...

Day 1 was easy. Radiohead. Day 2 however. This is where things get tricky. With Wilco and Rage Against the Machine both headlining at the same time... well, it's enough to make any Lolla-goer go crazy. Marcus talked with some fans about how they're making this difficult call.

Wow. Just wow. I know everybody and their mother has written about this show by now, but I had to throw my two cents in. I finally gathered a few moments to sit down in the tent here at Lolla and reflect on last night's Radiohead show. There was one unbelievable moment (probably the best concert moment I've been a part of to this point).....and a few irritations. But overall, it was everything it was built up to be. Just phenomenal. Keep reading!

Brendan from Broken Social Scene was kind enough to take time out of his day at Lollapalooza to have a lengthy chat with Jackie.

Outtakes from the interview (Brendan shows Jackie how he prepares for his show) and footage of their show after the jump.

When your lower on the bill at the biggest music fest in the universe, you sometime have to go the extra mile to get noticed. And sometimes it works. Jackie couldn't overlook De Novo Dahl in their eye catching ensem's -- turns out their stage show is just as unique.

Jackie catches up with singer songwriter Serena Ryder. Billboard Magazine recently named her "Canada's most promising."

Lots of crowds makes for lots and lots of garbage. But the festival is doing its part to make it easier for Lollapaloozians to keep earth friendly.

Perry Farrell and other Lollapalooza organizers met with the press to talk about the festival.

They also talk about helping to restore Buckingham Fountain, Radiohead's performance and the fest's killer lineup.

Dierks Bently, the festival's lone country act, talks to Marcus about performing for the Lolla crowd.

It's one big swelter block party at Grant Park with English indie rockers Bloc Party.

Gogol Bordello shows Chicago how it's done in New York City and performs for the over-heated masses in Grant Park.

In this sea of thousands of fans, one stands out and it's not because of his mohawk or exceptional mosh skills. In fact, looking at Jim Henke, you might think he's your average Lolla go-er, but his stories are anything but. As former music journalist for Rolling Stone and current curator of the Rock and Roll Hall of Fame, Henke has seen his fair share of concerts. Marcus found some shade and sat down with Henke to talk about what brought him to Lolla this year.
