“Stockholm” is a track from American band OSIs third studio album “Blood” from 2009.
The track features OSI members, guitarist/basist, Jim Matheos (Fates Warning) and keyboardist Kevin Moore (Chroma Key, Dream Theater), with the addition of drummer Gavin Harrison (Porcupine Tree, King Crimson) and vocals by Mikael Åkerfeldt (Opeth)
The Track was written by Matheos/Moore, lyrics by Åkerfeldt.
What I like about this particular track, is the buildup, melting of ambient almost electronic sound into a hard riff based metal toward the end.
Another nice example of melting ambient with elements from prog-metal, is Lunatic Soul, the solo project of Mariusz Duda, lead singer and creative force behind the Polish prog metal band Riverside. Lunatic Soul outputs in generally more calm than OSI’s, but there are hints of harder rock, here and there.
