This electro-pop uncle-nephew duo burst onto the scene with 2009’s "Shots," a song about getting totally obliterated. Two years afterward, they were still shamelessly getting wild but now insisting that everyone else join them in the fun. "I wanted a song for when we walked into a party, so I thought, 'Party rock in the house tonight/Everybody just have a good time,'" Redfoo (a.k.a. Stefan Gordy, son of Motown founder Berry Gordy) told Rolling Stone about the lyrics to "Party Rock Anthem." "The 'just' was key. I made it a command to focus people on what to do now that we’re here together."
