"Beyond the songwriting and the anomaly of having a band comprised of such virtuosos, for me 'Zeppelin's magic has always been about the chemistry that existed between the four members. The records they made always respected and cherished the fact that they were a live band, nothing was recorded 'perfectly' and things often sped up or slowed down but in unison. They were a one body made up of four vital limbs. Nearly fifty years on and the quality of the songs, the guts and the swag on these recordings is untouched. It's some of the most human and real music ever made in the history of rock and roll that no computer or technology in the world could come close to imitating." - Royal Blood
