The Days of Grays is the sixth full-length studio album by Finnish power metal band Sonata Arctica.

[7][8] It is the first album with guitarist Elias Viljanen and also the first since 1999's Ecliptica in which vocalist Tony Kakko also plays the keyboards.

Sonata Arctica keyboardist Henrik Klingenberg described the album as: a bit darker and maybe not so complex as [2007's] "Unia".

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".

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.
