Rap superstar Kendrick Lamar played a surprise concert Tuesday night atop a moving semi-truck in Hollywood.
Lamar tweeted fans the location of the truck just one hour before playing the concert.
From video footage of the event, it looks like fans had to jog behind the truck in order to catch the show.
Kendrick’s latest album, To Pimp a Butterfly, hit No. 1 on the Billboard 200 list this week after its surprise release last Tuesday.
