Jon Lord, British keyboardist, composer, and co-founder of Deep Purple, never played “background” the way polite musicians do—he attacked the keys like they owed him money, then turned around and wrote with the discipline of a trained composer. The story starts in the R&B trenches with The Artwoods (1964–1967), then detonates when he helps launch Deep Purple (1968–1976; 1984–2002), where that distorted Hammond became a lead instrument with teeth. After Purple’s first collapse, the road briefly rerouted through Paice Ashton Lord (1976–1978), and then straight into David Coverdale’s orbit with Whitesnake (1978–1984), adding class, weight, and that unmistakable “burning organ” halo to bluesy hard rock. Underneath all the volume, the man kept one foot in the concert hall—because some people can shred and still hear the orchestra in their heads.
