The death of legendary Deep Purple keyboardist Jon Lord has shaken the rock world through some of its most celebrated musicians. Among those who have tweeted their condolences are Slash, Mike Portnoy, Iron Maiden, Tom Morello and many more. Perhaps the most notable post however, comes from Black Sabbath bassist Geezer Butler.

In reaction to the death of Jon Lord, Geezer Butler shared his thoughts of the Deep Purple keyboardist. “Very sad to hear of Jon’s death, following his battle with the demon cancer,” begins Butler. “One of the great musicians of my generation. Tony Iommi recently worked with Jon, and said what a lovely bloke he was. I met him a few times, but never got to work with him. Blessings.”

Lord passed away after a long battle with pancreatic cancer, passing away at 71 from a pulmonary embolism earlier today (July 16.) Jon Lord may be most well-known for co-writing the Deep Purple classic ‘Smoke on the Water.’ The keyboardist dedicated over 25 years with the band, which finally split up for good in 2002.
