Math Bande son

Math rock is a rhythmically complex, often guitar-based, style of experimental rock and indie rock music that emerged in the late 1980s, 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, counterpoint, odd time signatures, angular melodies, and extended, often dissonant, chords.
