B-Complex aka Matia or Maťo Lenická (born May 9, 1984) is a Slovakian drum and bass music producer and DJ. In 2015, she came out as bigender, preferring the name Maťo when presenting as a man and the name Matia when presenting as a woman.
"Call me Matia (sometimes) - some of you know, some don't - I happen to be transgendered person as well, bi-gender in particular. I'm glad that the awareness about transgender is growing, thanks to Laverne, Caitlyn but also many other anonymous folk that may not share as much publicity. I have to thank to everyone during the years who helped me become who I am and supported me directly or indirectly."
