"On May 10, 1969, Led Zeppelin made their first appearance on the UK album chart when the band's debut album charted at No. 6, going on to spend 71 weeks on the UK chart. It entered the US chart the following week at No. 10. Recorded in around 36 hours, the album is now considered one of the most important debuts in rock, creating an entirely new interpretation of the Rock And Roll genre, with groundbreaking musical styles and recording techniques."
