Step 1 : Introduction to the question "Which of these bands released an untitled album?"
Led Zeppelin, in a bold and unconventional move, decided to release their fourth album in 1971 without an official title or even the band’s name on the cover. Frustrated with the media's focus on their image rather than their music, they wanted the music to stand on its own merit. Despite the band's intent to keep the album untitled, the public began calling it "Led Zeppelin IV" and it's been known that way ever since. The album features some of the band's most iconic tracks, such as "Stairway to Heaven," "Black Dog," and "Rock and Roll."
