• Sigma is a duo consisting of Cameron Edwards and Joe Lenzie, who first met at Leeds University in 2006 at drum and bass nights. Once they had finished in Leeds, the pair relocated to London and formed their own record label, Life Recordings.
  
  In 2010 Sigma hooked up with DJ Fresh to record "Lassitude." Released as the fifth single from Fresh's album Kryptonite it peaked at #98 on the UK Singles Chart.
  
  Sigma released their debut single "Rudeboy" in December 2013 after signing with 3Beat. That song reached #56 on the UK Singles Chart.
• This is Sigma's second single with 3Beat. Originally a bootleg remix of Kanye West's "Bound 2," it was released on January 24, 2014 for free download. After receiving support from major British radio stations the tune was reworked into an original track with Charlie Wilson's original vocal being covered by a session vocalist. The new version was dropped on April 6, 2014, topping the UK iTunes chart upon release.
• It was the hook of "Bound 2" that drew Sigma to rework the tune. Joe Lenzie told Digital Spy: "We loved the sound of the piano chords and the Charlie Wilson vocal and we just thought that could really work as a drum and bass track."
  
  "What we do when we have studio sessions is we spend a lot of time just listening to other stuff to try and see if we can get influence from different genres," he continued. "I think the fact that it was perfectly half speed for drum and bass as well that can be a big part of what's actually gonna work. You might hear something that's a great chord structure that you might think about remixing or whatever but if it's the wrong speed it just kind of kills the vibe."
• So what does Kanye West think of Sigma's reworking of the song? Joe Lenzie said: "His management contacted us asking if we'd be prepared to somehow put together some exclusive VIP thing that he was gonna perform when he played at Wireless, but I think it was so last minute and we were in Miami at the time filming the video for 'Changing,' so we ended up just not doing it basically. But I'm assuming that that means that he must like it in one way I guess."
• This was the first ever drum & bass track to hit 100 million YouTube views.
