Quote from Eddie Kramer who helped produce LZ II. “Jimmy Page was very demanding. I use the comparison to Jimi Hendrix – both very demanding, very clever and on top of their game. They knew what they wanted to hear. Page even more so – because of his experience as a session musician, he was directing everything. This was his deal; he was the creator of the whole concept. “That’s not to say he could have done it without the other musicians. Having the best drummer in the world and probably the world’s greatest rock bass player – one who was also a superb arranger and a master of many, many talents, like keyboards – that was key. You couldn’t imagine Led Zeppelin without the component parts; each component made the whole. And Robert Plant – you couldn’t put together a better rock dynasty than Zeppelin. “The echo in Whole Lotta Love was a mistake – it was one of the biggest mistakes I ever made. We were in the middle of the song, and it comes to the break – ‘Woman…’ And you hear another one – well, one of the other vocal tracks was breaking through because we were using this funky old console. It wouldn’t allow me to turn the vocal off; I couldn’t get rid of it. Page and I looked at each other at the same time, and we grabbed a knob and threw a shitoad of reverb on it. We laughed and said, ‘Let’s leave it.’ “That is a classic example of leaving the damn mistakes in, because you never know where it’s going to lead you.

The group that recorded "Becks Bolero" wouldn't have been the same without John Paul Jones either ? (sarcasm font)
