"... Aqualung was a difficult and very tense album to record... while I was playing the solo, Jimmy Page walked into the control room and started waving, I thought, should I wave back and mess up the solo or should I just grin and carry on ? ... I just grinned"

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.
