On 6 August 2014, it was announced that Nevalainen would not be able to take part of Nightwish's eighth album and its subsequent tour due to insomnia,[2] thus making the album Endless Forms Most Beautiful the first Nightwish recording without his participation. Nevalainen will still handle the day-to-day affairs of the band, though.[2] Kai Hahto (Wintersun) would be taking his place in the album and on the subsequent tour.[2]
