46 years ago, on this day, January 12th, the first studio album of Led Zeppelin was released this week in 1969, in US.

"Four of us got together in this two by two room and started playing. Then we knew - we started laughing at each other. Maybe it was from relief, or maybe from the knowledge that we knew we could groove together. But that was it. That was just how well it was going. The statement of our first two weeks together is our album. We cut it in 15 hours, and between us wrote 8 of the tracks. Our main problem was knowing what channel to take it along musically. Everyone in the group had such a high musical content we thought each of us would be into our own thing. But it all fell in together."

- Jimmy Page
