The duo that released the 2011 smash hit "Party Rock Anthem" was LMFAO.
LMFAO was the American electronic dance music duo of Redfoo and Sky Blu, who are uncle and nephew. The song became the lead single from their second and final studio album, Sorry for Party Rocking, released in 2011. Lauren Bennett provided featured vocals, while producer GoonRock also contributed vocals and songwriting.
Released as a single on January 25, 2011, "Party Rock Anthem" became LMFAO's signature song. It topped charts in the United States, the United Kingdom, Canada, Australia, and many other countries. Its music video helped popularize the Melbourne Shuffle with the recurring phrase "Every day I'm shufflin'." A common mix-up is crediting Lauren Bennett or GoonRock as the act; they were featured collaborators, but LMFAO was the credited duo.
