Progressive Metal: Whilst debatable as to whether it constitutes a descriptor or a genre in its own right,
Progressive Metal features tracks that consistently vary throughout the course of the song. Often more involved in exploring a thematic concept, a particular range of emotions or in telling a story; because of this nature the track will only come to an end when the subject matter has been covered in sufficient detail, sometimes including additional unconventional instrumentation where required to accentuate the point being made, the result is often longer tracks are performed.
A common misconception is that the style of music being formed pushes conventional boundaries, and whilst this may once have been true to an extent from a technical standpoint with the frequent inclusion of time signatures and unusual beat patterns over the more conventional
Rock and
Metal format, it is not this that defines
Progressive Metal. It is perfectly possible to have simplistic and catchy music that remains progressive (e.g.
Janne da Arc,
Walrus), if perhaps uncommon. Whilst any sub-genre of
Metal can display progressive tendencies, much of the genre is either strongly influenced by
Power Metal (e.g.
Symphony X,
Manticora,
Redemption) or
Death Metal (e.g.
Atheist,
Cynic, [later]
Death). Other well known examples include
Dream Theater,
Zero Hour and
Nevermore. -
TBTechnical/Math Metal: Often associated with
Progressive music, the genre utilises irregular song structures, dissonant chords, abrupt changes in tempo and unusual beat patterns. The result is often very complex and chaotic in tone, reserved largely for use in
Technical Death Metal (e.g.
Anata,
Gorguts,
Cryptopsy) and
Mathcore (e.g.
Sikth,
Rolo Tomassi,
Protest the Hero). Both genres terms emerged from alternate places but ultimately mean the same thing;
Mathcore emerging influenced primarily from
Math Rock and
Technical Death Metal taking influences from
Technical (Free) Jazz.
John Zorn - particularly with
Naked City - soon fused the more metallic
Technical Death Metal with the more punk influenced
Mathcore, and with a greater reliance on
Free Jazz, created a new breed of music called
Jazzcore (e.g.
Midori,
Kusudama,
Lye By Mistake). It should be noted that
Technical music is not always chaotic in its sound; if something is performed in a 7/13 beat pattern at 120bpm, it remains technical but neither quick nor complex (e.g.
Slint,
Crydebris). It should also be noted that
Technical music and
Progressive music are mutually exclusive terms. -
