Saturday kicked off the third annual Outside Lands Music and Arts festival in San Francisco and RadarOnline.com is bringing you all the action from the eco-friendly event in the middle of Golden Gate Park.

After a long, scenic walk to the main entrance, we blasted through the VIP tent (really, who wants to pay $10 for refreshments right off the bat!) to wander the expanse of the tents and stages in the Polo Field.

CONCERT PREVIEW: Rocking Out At Outside Lands 2010

As the sun peeked through the fog at 2 PM, the Afro beat folk strains of Sierra Leone's Refugee All Stars competed with the metal sounds of Ground Control as the crowd noshed on beers and food from cajun sausage and calamari. With the crowd capacity still on the light side, one of the bigger draws besides the acts on the big stage was the tipsy concertgoer taking control of the karaoke machine in one of the experience tents. He was so bad he was good and drew a small gathering.

Next stop: the Chase Freedom Lounge (which is open to all Chase Freedom ) where the faux hardwood floors indoors and leatherette couches were a nice change of pace from the gravel, grass and dirt de rigueur of outdoor music events. For those who took the extra step and redeemed their Chase Freedom points for concert admission, the outdoor VIP area offered free sandwiches, drinks, and a luxe respite from the other-wise rustic offerings.

Nestled in the Speedway Meadow section, the lounge also offered an extra delightful bonus: exclusive, deluxe, tiled bathrooms that were line-free!

By 4 pm, the crowds finally began rolling in and filling up the grounds. At the Polo Field Sutro stage, Bassnecter- the hometown boys from SF specializing in freefrom electronica- got the capacity crowd rocking. Despite the chill, the most ardent fans whipped off their shirts and threw their arms up jamming to the hip-hop infused beats and bumps. As the last screams of their "West Coast" chants faded away, the crowd took a few last swipes at the black beach balls being passed around as they gave one last cheer for the band.

Back at the Speedway Meadow Panhandle stage, the Rebirth Brass Brand brought some true Southern flair. At 5:15, the band burst into a lively rendition of "Do Watcha Wanna," the theme song for the new HBO show Treme. The crowd howled as the band broke into the recognizable chorus, swaying their hips and stamping their feet in joyous unison.

At 6:00, it was back to the Chase Freedom lounge for an intimate performance from country rocker Langhorne Slim. Fans eager enough to get to the show early got a special treat: some of the band hung out by the stage chilling with the banjo player strumming some chords to warm up.

Nightime has descended and it's time to catch the last big acts of the day: Cat Power at the Speedway Meadow Twin Peaks stage and The Strokes who will close out day one right after (more on them in tomorrow's blog from Outside Lands!).
