Post-rock (Postrock) is a genre that pushes the boundaries of traditional rock music, emphasizing atmosphere, texture, and dynamics over conventional song structures and lyrics. Emerging in the 1990s, it often features expansive, instrumental compositions that build gradually, using guitars, drums, and other instruments to create intricate soundscapes. Bands like Mogwai, Explosions in the Sky, and Godspeed You! Black Emperor are key pioneers of the genre, blending elements of ambient, classical, and experimental music. Post-rock invites listeners into a cinematic and introspective experience, prioritizing mood and emotion over straightforward storytelling.
