She was discovered in 2003 after winning Australian radio station Triple J's Unearthed talent contest. Vassy was the first Australian solo artist to reach the #1 spot on the US dance charts when her single "We Are Young" reached the top of Hot Dance Club Songs.

• Showtek explained how the collaboration came about in a November 2014 interview with Billboard magazine. "Last year, David invited us to support him at Pacha Ibiza, and after a few times, he invited us to his home studio to listen to music," they said. "He was the first artist we ever showed Booyah' to, and he was crazy about it."
  
  "He said we needed to work on a track together," they continued. "He was working on his album when we met him, so he had so many songs and so many ideas. He said, 'Let's do something together and see where it ends up.' So we did 'Bad' together, which is one of the songs on his album."
