Math rock is a style of alternative and indie rock with roots in bands such as King Crimson and Rush. It is characterized by complex, atypical rhythmic structures, counterpoint, odd time signatures, and extended chords. It bears similarities to post-rock.
Steve Albini is an influence in the math rock genre.
Post-rock is a form of experimental rock characterized by a focus on exploring textures and timbres, as well as non-rock styles, with less emphasis on conventional song structures or riffs. Post-rock artists typically combine rock instrumentation with electronics. The genre emerged within the indie and underground music scene of the 1980s and early 1990s. However, due to its abandonment of rock conventions, it began to increasingly show little resemblance musically to conventional indie rock at the time, borrowing instead from diverse sources including ambient, electronica, jazz, krautrock, dub, and minimalist classical, with these influences also being pivotal for the style of ambient pop.
