Sia Furler, Adele Adkins, Tobias Jesso Jr.
"Alive" is the lead single from Australian singer and songwriter Sia's seventh studio album This Is Acting (2016). It was co-written by Sia, Adele, and Tobias Jesso Jr. The song was produced by Jesse Shatkin. "Alive" was released on 25 September 2015. The song was originally intended for Adele's third studio album, 25, along with "Bird Set Free". However, since Adele decided not to use the songs, she let Sia use them for her seventh studio album. Musically, it is a midtempo pop and synth-pop song.
