math rock 

Math rock is a very loosely defined genre of music. The term is hard to describe and often misused. However, one good way to describe it is as a style of rock that has almost no trace of folk or blues, which is the traditional definition of rock. Instead, the sound may have a loose, jazzy-like and spontaneous feeling, in contrast to the direct and compelling sound of blues and folk. At the same time however, the music is also calculated, and instrumental riffs are often based on timed formulas. For example, a guitar riff may repeat a sequence of five quarter-notes over 4/4 time signature, thus giving the listener an overall feeling of chaos, in spite of the riffs rigid structure.

The genre is gaining more influence, especially in the Los Angeles area. Bands like The Blood Brothers, Plot to Blow Up the Eiffel Tower, and An Albatross are some of the most famous math rock bands.

math rock/metal 

n.

1. A term that encompasses most all modern progressive rock or metal that places emphasis on time signature modulation and meter as opposed to dynamics, melody, or harmony. "Math rock/metal" encompasses everything from the jazzier leanings of post rock act Slint, to the phrase swapping and odd meters of the Dillinger Escape Plan, and even the hemiola and polyrhythm experiments of bands like Meshuggah and Tool.

2. A term often falsely described as "intelligent music" by people who simply regurgitate what they are told and apparently have no idea how to count.

Math rock/metal requires concentration.
