Bonnaroo: 10 Things Seen & Heard Thursday

Krispy of The Knux crowd surfs when performing at Bonnaroo on Thursday, June 9.

The 10th annual Bonaroo festival kicked on Thursday night in Manchester, TN with enthusiastic crowds, sweltering temperatures and hot sets from a host of buzzworthy indie and hip-hop acts, including Twin Shadow, the Walkmen, Deerhunter, J. Cole, the Drums and more. Here's a few things we saw and heard on the grounds and backstage on day one of the 4-day fest.

Bonnaroo 2011's Top 10 Performances

1. To commemorate Bonnaroo's 10th anniversary, portraits of past headliners, painted as stylized grafitti, were scattered on the baracades near the main stages. Pics of Jay-Z, Bob Dylan and Wilco's Jeff tweedy were among the most eye-popping portraits.

2. Best Coast's Bethany Consentino lovingly gave her bf, Wavves' Nathan Williams, the middle finger as he passed by her in the artist area.

3. Donald Glover told J. Cole that he was a fan and that he would catch his set that night when he met the rapper during the afternoon. J. Cole appreciated the kind words from the rapper/comedian. We also hear that Donald Glover's proper debut album will be released in September, the same month his NBC show "Community" returns for a new season.

4. Sophia Bush from "One Tree Hill" was on the side of the stage for School of Seven Bells, snapping photos with a professional camera.

5. Before Childish Gambino took the stage, a chilled-out girl in the crowd decided to spin her light-up hula hoop around her waist for 20 minutes straight.

6. The longest line of the night might not have involved music (or food, or bathrooms) at all: dozens of fans flocked to the Bonnaroo Sports Bar to watch Game 5 of the NBA Finals between the Miami Heat and Dallas Mavericks. A ton of Dirk Nowitzki jerseys could be spotted in Thursday's crowd.

7. Jack White was spotted backstage at soon-to-be-ex-wife Karen Elson's set, watching on with the couple's baby.

8. Sleigh Bells came onstage after a disturbingly long soundcheck, and fans in the front row were thrashing and passing out left and right during the intense set.

9. Eminem songs traveled far and wide during an early afternoon sound check for his Saturday night headlining show. A group of fans even started singing "Not Afraid" as an a cappella version blasted from the What Stage.

10. Anti-drug enforcement seems to be pretty lax: during J. Cole's set, an adventurous festival goer could be seen walking around screaming, "Who has weed!?" at the top of his lungs.
