Endless Forms Most Beautiful is the upcoming eighth album by Finnish symphonic power metal band Nightwish. It is due to be released on March 27, 2015 in the EU, on March 30 in the UK and on March 31 in the USA. It is the first album of the band with new singer Floor Jansen, as well as the first to feature Troy Donockley, who played uillean pipes and various other instruments on Dark Passion Play and Imaginaerum, as a full-time member.
It is also their first album without drummer Jukka Nevalainen, who had to take a temporary break from the band due to suffering of strong insomnia, leading him to step away from both the album and its subsequent tour. All the drum parts of the album were consequently played by Kai Hahto from Wintersun and Swallow the Sun; due to this, this album features only five Nightwish members, despite being their first album released with the band being a sextet.
The first single from the album, titled "Élan", will be released on February 13, 2015.
