Siberia is the second studio album by Canadian singer-songwriter Lights. It was released worldwide on October 4, 2011, excluding Australia and the United Kingdom. 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 synth-pop, it also features influences of other genres such as dubstep, hip-hop, and bitpop.
