Sigma Vinyl Records
Formed while at university in Leeds, the U.K. drum'n'bass act Sigma soon relocated to London and initially comprised Cameron Edwards, Joe Lenzie, and Ben Mauerhoff. Following a spate of well-received singles from 2006 onward on labels such as Mampi Swift's Charge and DJ Zinc's Bingo Beats, Mauerhoff decided to leave Sigma, eventually establishing himself as a Shanghai-based sound designer for the video industry.
