Listen to Radiohead Radio on iHeartRadio

Radiohead wasn't at Lollapalooza this weekend, but Thom Yorke did make an appearance at Leopalooza. 

The frontman played an unannounced DJ set at the small U.K. festival, which usually features a lineup full of new, underground, and homegrown acts.  The event's organizer tells Pitchfork Yorke is a good friend of the festival, adding that he "understands the DIY ethos of this independent event." 

Thom played last year's Leopalooza as well, but his return this year was kept quiet so as not to overshadow the other acts playing around the same time.  Only about 30 people were on hand for Yorke's set, which also reportedly included a bit of the singer's famous dancing.
