If you wanted to chart new territories and head off over the horizon, you had to make sure you weren't overly influenced by what others were doing ... so it didn't matter what other bands were doing ... we did what we were doing.

I bet you can't play slide piano.

I don't like being stuck in one situation, day to day.

We kept moving forward and didn't try to recreate the past .. the approach to each album was radically different every time. Many bands would have some success and, because they were locked into having a single - something we didn't have to worry about - they had to make sure there was something similar on the next album ... that was never the idea with Led Zeppelin .. the goal was to keep that spark of spontaneity at all times.

I feel Aleister Crowley is a misunderstood genius of the 20th century. Because his whole thing was liberation of the person, of the entity, and that restrictions would foul you up, lead to frustration which leads to violence, crime, mental breakdown, depending on what sort of makeup you have underneath. The further this age we're in now gets into technology and alienation, a lot of the points he's made seem to manifest themselves all down the line.

I'm very fortunate because I love what I'm doing.

Music can always be a life-changing experience, for musicians and fans, or at least life-affecting, but it depends on to what degree.
