芬兰旋律/力量/交响金属乐团Nightwish即将由Nuclear Blast Records发行乐迷眾所期待时隔4年之久的第七张录音室专辑"Imaginaerum”，芬兰/日本地区将抢先在2011年11月30日上市。12月2日（欧洲其他地区）。专辑在北美地区将由Roadrunner Records发行。
Nightwish的灵魂人物，键盘手/词曲创作Tuomas Holopainen表示：“最初这应该是专辑的一张内页插图，但是有一次我和团员们看到了最后完成的图画，我们立刻就知道了我们一直苦苦寻找的专辑封面就在这了。我相信这是Toxic Angel(芬兰插画设计师)最棒的一幅作品，捕捉到了´Imaginaerum´最实质的精髓。这充满了想像力，这是无言的奇观，充满了魔法与敬畏，渴望与超现实。

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.

Japanese pressing includes one bonus track. Marquee. 2009.
