In 1995, Paul D’Amour decided to depart Tool. With a studio album, EP and five years service under his belt, he left the prog rock institution he had helped found and launch, passing the bass guitar torch to his successor: Justin Chancellor.
Chancellor has remained a member of Tool ever since, going on to become one of prog-metal’s most celebrated and popular bassists after first making his debut on 1996’s Ænima.
