Antony/Sia 'One Candle' / 'Manta Ray' (with J. Ralph)
This summer, images of endangered species were projected on the Empire State Building in New York, and the stunt was soundtracked by songs from Sia and Antony (of Antony and the Johnsons). Soon, those songs will appear in the environmental documentary Racing Extinction.

Both songs were created with composer J. Ralph, who scored the whole doc. Antony sings "Manta Ray," a waltz-time ballad in which the vocalist's tender vibrato flutters atop Erik Satie-style piano playing and subtle orchestrations. Sia's "One Candle," on the other hand, is a buzzing, dramatically upbeat synth-pop anthem. Both of the songs have lyrics that are directly relevant to the film's environmental message about species extinction.

Racing Extinction will air on the Discovery Channel on December 2.
