Celestica is the first single from Crystal Castles' second self-titled album, Crystal Castles. The single was released digitally as an EP, featuring the three B-sides on the Doe Deer 12" EP. This single also included a "Single Mix" of "Celestica". A no-budget video for the track was released as well, directed by Rob Hawkins, a friend of the band. No official artwork has been presented for the single.
The song is said to have some relation to the Canadian factory Celestica in which Ethan Kath said that one of the workers allegedly committed suicide by jumping into a tub of hot plastic and that they still used the plastic to make products.
