第八乐章 (2005)

Octavarium is the eighth studio album by American progressive metal band Dream Theater. Released on June 7, 2005, it was the band's final release with Atlantic Records. Recorded between September 2004 and February 2005, it was the last album recorded at The Hit Factory in New York City. With it, the band decided to create "a classic Dream Theater album", drawing upon their various stylistic influences while trying to make the music less complex. The album takes its creative concept from the musical octave.

Octavarium peaked in the top five in the Finnish, Italian, and Swedish charts, and in the top ten in the Dutch, Japanese, and Norwegian charts. Critical reception of the album was generally positive; the diversity of the music was praised, although critics found some of the songwriting to be inconsistent. Dream Theater promoted the album on a year-long world tour, with the majority of concerts lasting almost three hours and featuring a different set list each night. The tour finished at Radio City Music Hall accompanied by an orchestra; this performance was recorded and released as a live album and concert video entitled Score. They co-headlined the 2005 North American Gigantour with Megadeth.

Background

After completing a North American tour supporting one of their main influences, Yes, in summer 2004, Dream Theater took a two-month break. The band reconvened at The Hit Factory in New York City in November 2004 to begin work on their eighth studio album.

After writing the concept album Metropolis Pt. 2: Scenes from a Memory, the double album Six Degrees of Inner Turbulence and the metal-focused Train of Thought, the band decided to create "a classic Dream Theater album". Keyboardist Jordan Rudess described it as "really going back to creating a real band effort, as well as drawing upon all our various stylistic influences." On Octavarium, the band wanted to make the music less complex, featuring songs which Rudess regards as "quicker to appreciate", although noted that the twenty-four-minute "Octavarium" was not as accessible. Guitarist John Petrucci noted that they wanted to focus on writing strong songs. To achieve this, the band stripped the sound down to piano, guitar and vocals when writing, focusing on the melodies and song structures.

Drummer Mike Portnoy dismissed claims that Octavarium was an attempt to write a more commercial album, stating that the band simply "[has] that side to [them]. We love bands like U2 or Coldplay, as well as liking shorter songs." Portnoy noted that, after writing Six Degrees of Inner Turbulence and Train of Thought, they had not written an album of shorter songs for some time. He said that the band had found writing longer songs easier than writing shorter ones, and that the band was not trying to write a radio hit as "the label wouldn't have done crap with it anyway."

The band had previously written an orchestral-style piece in the form of "Overture" on Six Degrees of Inner Turbulence, but Jordan Rudess recorded these using two keyboards: his Kurzweil K2600 and Korg KARMA, the latter a then-new synthesizer that Rudess had bought fairly recently. The tracks "The Answer Lies Within", "Sacrificed Sons" and "Octavarium" marked the first time Dream Theater worked with an orchestra, conducted by Jamshied Sharifi (who later conducted the Octavarium Orchestra on Dream Theater's 2006 live album Score). The orchestra was selected based on their sight reading ability, allowing all their parts to be recorded in a maximum of two takes, even though they had never seen or played the music before.

Concept

When starting to work on what would become Octavarium, Portnoy noted that it would be their eighth studio album and that they had recently released their fifth live album, Live at Budokan. This sequence mirrored the octave on a musical keyboard: each octave contains eight naturals and five accidentals. Portnoy suggested that they use that concept for the entire album. When writing, the band delegated each song a different key. Sound effects were placed between songs to connect them: for example, "The Root of All Evil", written in F minor, and the following track, "The Answer Lies Within", written in G minor, were connected by a sound effect in the key of F♯ minor. The album's lyrics and song titles featured references to this concept. Portnoy cited the titles "The Root of all Evil" (referring to the musical term "root") and "Octavarium" ("the octave of the octave") as two examples of this.
