Outside Lands Friday recap: Tove Lo flashes the crowd, Gorillaz nail star-studded set

San Francisco's Golden Gate Park is bumpin' with more than 200,000 guests this weekend as Outside Lands Music and Arts Festival marks its 10th year.

All was off to a strong start on Friday, despite one hiccup in the lineup: A Tribe Called Quest was forced to postpone its highly-anticipated performance until Sunday due to travel issues, organizers confirmed around midday. But even with that gap, it was a high-energy day stacked with stellar sets:

Tove Lo riled up the crowd during her performance of "Talkin' Body," during which she teasingly lifted up her top, eventually fully exposing her breast, much to the audience's approval. The move likely didn't come as a huge shock to devoted fans, as the Swedish pop star did the same routine at this year's Lollapalooza.

Gorillaz, one of the biggest headliners of the weekend, pulled out all the stops during a nearly two-hour set, inviting a slew of guests to join on stage: Kali Uchis, Pusha T, Anthony Hamilton, Pos from De La Soul, and Yukimi from Little Dragon all made surprise appearances as he played his new album "Humanz." His classic hits -- "Stylo," "Feel Good Inc" and "Clint Eastwood" rounded out the finale.

Lesser-known but growing in popularity, indie-rock group alt-J had three albums of material to pull from, taking the stage after a strong set from indie-folk act Fleet Foxes.

Our live stream continues Saturday and Sunday with performances from Lorde, Metallica and The Who.
