OK Computer (1997) is Radiohead's landmark third studio album, critically acclaimed for its prescient exploration of 21st-century anxiety, technological alienation, and consumerism. Moving away from traditional rock, it features atmospheric, melancholic soundscapes, iconic tracks like "Paranoid Android" and "Karma Police," and is considered one of the greatest albums ever made. 2-disc version includes the original album + B-sides and unreleased tracks.
