Progressive metal (sometimes shortened to prog metal) is a broad fusion music genre melding heavy metal and progressive rock, combining the loud "aggression" and amplified guitar-driven sound of the former with the more experimental, cerebral or "pseudo-classical" compositions of the latter. One of these experimental examples introduced to modern metal was djent. The music typically showcases the extreme technical proficiency of the performers and usually uses unorthodox harmonies as well as complex rhythms with frequent meter changes and intense syncopation.
While the genre emerged towards the late-1980s, it was not until the 1990s that progressive metal achieved widespread success. Queensrÿche, Dream Theater, Tool, Symphony X, Shadow Gallery, King's X, and Fates Warning are a few examples of progressive metal bands who achieved commercial success. Soon after the rise of the genre's popularity, other thrash and death metal bands started to incorporate elements of progressive music in their work.
Progressive metal, as a distinct musical style, was primarily advanced by members of the American heavy metal scene of the mid-1980s, particularly Queensrÿche, Fates Warning and, later, Dream Theater. It has since developed in a non-linear fashion, with countless groups demonstrating innovations in personal ways.
The origins of the genre date back to the very beginning of heavy metal/hard rock and progressive rock when some bands began to merge the two different approaches. 1960s pioneers King Crimson maintained their musical innovation while incorporating a harder approach, using dissonance and experimental tones, yet still maintaining a relationship to the power chords of hard rock, with the main example being 21st Century Schizoid Man. Canadian trio Rush are widely recognized as bridging the gap between hard rock, English progressive rock, and pure heavy metal. Initially influenced by Led Zeppelin, they evolved to combine established progressive rock technique with blues-based power chords. Records such as 2112 (1976) showcased technical expertise and complex compositional skill while still utilizing a more direct and heavier approach than the established English progressive rock music.
1984 brought full length debut albums from American bands Queensrÿche, from Washington state, and Fates Warning, from Connecticut. Both expanded their music to include more progressive elements (The Warning 1984, The Spectre Within 1985) – some through sound experimentation and compositional refinement, others through extremely complex structures and atypical riffs – up to the two seminal works in 1986: Rage for Order and Awaken the Guardian. In the following years the two bands, while following different paths – more basic and simple the first, more articulate and complex the latter - explore and expand the technical refinement and sonic finesse of their music, continuing to lay the foundations of the genre with important works such as Operation: Mindcrime (1988) by Queensrÿche, and Perfect Symmetry (1989) by Fates Warning.
Progressive metal also found a home in the growing U.S. speed metal movement, influencing popular heavy metal bands Metallica - ...And Justice for All (1988). Among the other pioneering thrash metal bands, one of the most important is the Canadian Voivod, with their complex and experimental style, full of psychedelic dissonances (Dimension Hatröss 1988, Nothingface 1989). "Math-metal" pioneers Watchtower, from Texas, took the concept of time-changes to a new level, combining thrash metal, syncopation and prog in their albums Energetic Disassembly (1985) and Control and Resistance (1989), giving rise to an extremely technical approach based on the rhythmic deconstruction typical of jazz fusion. This same type of prog metal would be later integrated into death metal by bands such as Atheist (1991's Unquestionable Presence), which would become known as technical death metal or progressive death metal.
The major US bands that contribute to further delineating and developing the genre are Psychotic Waltz and Dream Theater. The former, with an approach halfway between Watchtower and Fates Warning, produced A Social Grace (1990), melding their signature sound with the psychedelic Into the Everflow (1992), while the latter explored the legacy of the bands that preceded them while advancing their personal style with When Dream and Day Unite (1989). Both albums focused on keyboards and band members' instrumental skills, and their efforts resulted in two fundamental albums, that institutionalize classic progressive metal - Images and Words (1992) and Awake (1994).
As for Europe, among the pioneers are the Germans Sieges Even, who, starting from the techno thrash of Watchtower, explore the more technical and angular side of progressive metal with The Art of Navigating by the Stars (2005).
Among the bands of the late 1990s who brought innovation to the genre are the Dutch Ayreon (a project by Arjen Anthony Lucassen) and the Swedes Pain of Salvation. Ayreon focused on theatrical and melodramatic rock operas Into the Electric Castle (1998) and The Human Equation (2004), performed by many different members of prominent metal bands. Pain of Salvation was always working towards an unusual style, demonstrated by the eclecticism and anti-conformism found on One Hour by the Concrete Lake (1998), and BE (2004). Forerunners of a more experimental and alternative approach include Thought Industry, as seen in their album Mods Carve the Pig: Assassins, Toads and God's Flesh (1993).
Puerto Rican band Puya rose to prominence in the late '90s with their innovative fusion of jazz, salsa, and progressive metal, evident on their 1999 album Fundamental.
Between the Buried and Me, who started as a more straightforward metalcore band, began to incorporate both progressive metal and death metal into their music on their 2003 album The Silent Circus, a landmark album in the progressive metalcore genre. They would later add avant-garde elements as well on releases such as The Great Misdirect (2009).
One of the hallmark musical qualities of progressive metal is eclecticism. In between the riffs, choruses, and solos typical of rock and metal songs, prog metal bands often include sections inspired by jazz, classical and Middle Eastern music, among others. Progressive metal is difficult to define specifically, since most bands labeled under the genre have considerably different musical influences when compared to each other.
Similarly, bands such as Dream Theater, Planet X, Puya, Liquid Tension Experiment, The Faceless, Between the Buried and Me and Animals as Leaders have a jazz influence, with extended solo sections that often feature "trading solos". Cynic, Atheist, Opeth, Between the Buried and Me and Meshuggah all blended jazz fusion with death metal, but in dramatically different ways. Devin Townsend draws on more ambient influences in the atmosphere of his music. Progressive metal is also often linked with power metal; Fates Warning and Conception, two bands that were originally power metal outfits, later incorporated progressive elements that ended up overshadowing their power metal roots. The ProgPower music festivals showcase this progressive/power metal fusion. Recently, with a popularity in shred guitar, the genre of "technical metal" has become increasingly prevalent and popular. This has led to a resurgence of popularity for more traditional progressive metal bands like Dream Theater and Symphony X; it also has led to the inclusion within the progressive niche of bands that do not necessarily play in its traditional style such as thrash/power metal band Nevermore and technical death metal pioneers Obscura. These bands are often labeled progressive since they play complex and technical music which does not fall under any other genre.
In the late 2000s, bands such as Periphery, Tesseract, Animals as Leaders and Vildhjarta popularized the "djent" style of progressive metal in a sound originally developed by Meshuggah. It is characterized by high-attack, palm-muted, syncopated riffs (often incorporating polymeters), as well as use of extended range guitars. Extended range guitars also feature in other forms of progressive metal; artists including Devin Townsend, Dir En Grey, and Ne Obliviscaris have used 7-string guitars without being part of the "djent" movement.
Proyecto Eskhata, a Spanish band, has received much press coverage in Spain for its fusion of progressive rock and rap metal, which journalists have described as "progressive rap metal".
Progressive doom is a fusion genre that combines elements of progressive metal and doom metal. Bands include King Goat, Below the Sun, Sierra, and Oceans of Slumber.
