Siberia is the second studio album by Canadian recording artist Lights. It was released worldwide on October 4, 2011, excluding Australia (October 28, 2011) and the United Kingdom (March 12, 2012). Production was handled by Tawgs Salter and Canadian electronic band Holy Fuck, while featuring guest vocals from Canadian rapper Shad on two of the album's tracks. Musically, Siberia has been described as being "grittier" and "darker" whilst also incorporating "poppier moments", and while the album still uses prominent elements of synthpop, it also features influences of other genres such as dubstep and hip-hop and bitpop.
