10 Best Progressive Rock Albums Of The 2000s

Dream Theater's aptly named eighth effort saw the group return to their roots. Looking to simplify their sound, 'Octavarium' functions almost as a secret greatest hits collection, touching on the many notes and tropes the group have used to establish their prominence over the years.

The result is an eclectic, often unpredictable 75-minute masterclass in the heavier side of modern prog rock. In classic prog fashion, the album boasts two multi-part epics for listeners to dive into and dissect.

First up is opening track 'The Root of All Evil', the third part in the group's multi-album 'Twelve-step Suite'. The track finds drummer Mike Portnoy in a dark place lyrically as a part of the Suite's emphasis on addiction and the twelve steps used by those in groups such as Alcoholics Anonymous. At just over eight minutes, it's actually the shortest entry in the series but packs a melodic, moody punch.

Second is the closing titular track, a 24-minute epic that captures the technical wizardry and innovation the Boston rockers have become known for. With five atmospheric parts to sift through and be wowed by, 'Octavarium' calls back to the long form rock odysseys of early prog legends like Pink Floyd.

Overall, 'Octavarium' is a perfect showcase album from one of prog's darkest and most confronting outfits.
