Radiohead's fourth studio album Kid A (released October 2, 2000) departed from the group's earlier releases, featuring more slippery, ambient electronic sounds. Rolling Stone called it the "weirdest hit album of that year, by a band poised to be the modern-rock Beatles, following the breakthrough of OK Computer." The magazine also named it the best album of 2000. It was Radiohead's first album to hit number one on Billboard. Steven Hyden, Uproxx cultural critic and author of the book, This Isn't Happening: Radiohead's "Kid A" and the Beginning of the 21st Century, discusses the album's legacy, and listeners call in to share what Kid A means to them.
