Endless Form Most Beautiful is the eighth studio album by Finnish symphonic metal band Nightwish. It was released on March 25, 2015 in Japan, according to Wikipedia. The Wikipedia entry explains that this album was written by Tuomas Holopainen, who has sung with the band since 2002, and bassist Marco Hietala, the secondary songwriter.

While most albums have a modern connection, Endless Form Most Beautiful, according to Albums Inspired by Books – Kenton County Public Library, is one of many albums that has a more historical connection. “It is probably safe to assume that there are not many albums influenced by evolutionary biology,” the article says. “However, the Finnish symphonic metal band Nightwish followed such a path for its 2015 album entitled Endless Forms Most Beautiful. The title comes from a line in Darwin’s On the Origin of Species.

Famous biologist Richard Dawkins reads short passages from his books on evolution as an introduction to some of the songs.” Some lyrics of Hietala appear on the album, but Holopainen composed the new album while he was writing the songs for his first solo album, music inspired by the life and times of Scrooge.

I heard one of the songs while I was researching the album. I think it's nice. It is soft and
a bit loud. Floor Jansen has been the band’s lead singer since 2013. I like her voice. She sounds like an angel. The sounds were good, too. Honestly I liked it and it was pretty cool.
