I had recently acquired an innovative piece of equipment, the Eventide Clock Works Harmonizer and I discovered one setting where you could arrive at a steel drum sound. I wanted to employ this colour, if possible, in the palette of John Bonham’s drum orchestra project. He really liked it and it’s quite heavily featured in the construction of the piece. When it came to be mixed, I used the keyboard with the Harmonizer to construct the final gliss-phrases. The percussion employed on this track with John Bonham’s kit were overdubbed bass drums, snare drums, tom toms, timpani, timbale, congas, backwards echo and Harmonizer.I am sure John’s inspiration came from the Brazilian Samba schools.

Also on this day in 2007, Led Zeppelin announced that they were to play the O2.
