Math Rock

Math rock is a rhythmically complex, often guitar-based, style of experimental rock and indie rock acts that emerged in the late 1990s, influenced by progressive rock bands like King Crimson and 20th century minimalist composers such as Steve Reich. It is characterized by complex, atypical rhythmic structures (including irregular stopping and starting), counterpoint, odd time signatures, angular melodies, and extended, often dissonant, chords.
