Élan by Nightwish

"Élan" is a single by Finnish symphonic metal band Nightwish, the first from their eighth album Endless Forms Most Beautiful. The song marks the first Nightwish song to feature its newest frontwoman, Dutch singer Floor Jansen, on vocals, and also the first to feature Troy Donockley as a full-time member and Kai Hahto as a temporary replacement for Jukka Nevalainen. The song was announced on December 8, 2014 at the band's official website. According to keyboardist and songwriter Tuomas Holopainen, the song is "a wonderful teaser for the full-length album, giving out a little taste, but revealing very little of the actual journey of grandeur to come." The music video for the song features several famous Finnish actors and was "inspired by the untold stories of abandoned places around Finland".The single also contains the song "Sagan", a bonus track not released on Endless Forms Most Beautiful. The song is about astrophysicist and science popularizer Carl Sagan. Tuomas said the band intended to include the track in the album track-list, but it would exceed the 80-minutes limit of a conventional CD, so they left the track out of it.
