a bit darker and maybe not so complex as [2007's] "Unia". Nevertheless, it's definitely not a back-to-the-roots album with fast power metal. All the trademark SONATA stuff is on there, solos, lots of singing [and] some slower songs.
The first single from the album is "The Last Amazing Grays". It was released by Nuclear Blast Records only in Finland on August 26. The band ran a fan art contest to choose the artwork for their second announced single, "Flag in the Ground" which the press release calls "an uplifting story about a young couple fighting their way to freedom and their own land in North America back in early 1800s." The winner of the contest was Simo Heikkinen from Finland. The name for The Days of Grays apparently took a very long time to come to as the band had a name for the record that was deemed more appropriate "for a death metal band or something" according to Henrik Klingenberg. In a French interview, Tony Kakko stated that the original name was Deathaura, the name of a song on the album.
"Everything Fades to Gray" features the lyrics "It's not fair, it's not fair, there was a time now" relating to the Twilight Zone episode Time Enough at Last and "The Truth is Out There" is about the popular TV series The X-Files.
