Led Zeppelin is releasing a new YouTube series to celebrate their band's 50-year-old history.
The first episode concentrates on the recording of the first self-titled debut album in September 1968. You can watch the one-minute video below.
The video features live footages of the band live performing with facts on how the first album came to be. Guitarist Jimmy Page said that the group had only been together for two and a half weeks when they recorded the album.
Bassist John Paul Jones added that the band "did it in about 15 hours" and spent another 15 hours on mixing, totalling up to 30 hours to produce the first album including the cover artwork. The total cost would be £1,782.
