Post-rock is a form of experimental rock characterized by a focus on exploring textures and timbre over traditional rocksong structures, chords or riffs. Post-rock artists are often instrumental, typically combining rock guitars and drums with electronic instruments. This genre often bears little resemblance musically to contemporary indie rock, borrowing instead from diverse sources including ambient music, electronica, jazz, dub and minimalist classical. The term post-rock was coined in 1994 by music critic Simon Reynolds. Some prominent names of this genre are God Is An Astronaut, Neurosis Pelican, Sigur Rós, Mogwai, Explosions in the Sky, 65daysofstatic, Red Sparowes, A Silver Mt. Zion.
