Celestica (song)

"Celestica" is a song recorded by the Canadian electronic music duo Crystal Castles for their second studio album, Crystal Castles (2010). Polydor Records released it as the album's first single on April 16, 2010, a day after its premiere on BBC Radio 1. A music video recorded at the Abney Park Cemetery was released in June. The song was written by members Ethan Kath and Alice Glass, with production handled by Kath. According to him, "Celestica" was inspired by a suicide at Celestica, a Canadian electronics company.

Critics cited the song as a shift from Crystal Castles' usual noisy sound, instead presenting a pop sound that resembled shoegaze. Others highlighted its melody and member Alice Glass's vocals. NME considered it one of the best songs of the year, while Pitchfork named it as one of the best tracks between 2010 and 2014 and among the best Crystal Castles songs.
