As the late Irish blues-rock guitar legend Rory Gallagher's guitars come up for auction this October at Bonhams in London, we caught up with Joe Bonamassa to play Rory's much-modded '59 Esquire while it was in New York being exhibited to the public – a pillar of Rory's slide guitar sound throughout his career – and hear his perspective on a player who embodied pure adrenalin and soulful intensity through his extraordinary career and also learn why Rory, as a guitar player, was about more than just that iconic '61 Strat.
