The most underrated musician in the band, John Paul Jones. However his credentials are staggering. His enormous contribution to music history traces back to his sessions days, working as a bass and keyboard player, arranger and musical director. The list of artists he was involved with features a wide range of British talent such as: Rolling Stones, The Yardbirds, Donovan, Jeff Beck, Herman's Hermits and many more. He was the first to be recruited by Page who was looking to form a new band, as Jones was growing tired of all the different band sessions.The magical chemistry of Led Zeppelin was created between all four members. One of the elements that made Led Zeppelin so great was their constant musical development and progress that was evident with each album. Finally, Jones is the only remaining member that has continued to progress and experiment with new styles and directions, without concern for commercial or critical success.
