RIP Joey Jordison, aged just 46. I was lucky enough to see Slipknot live and the speed of his drumming was incredible, I was even luckier to see him drum for Metallica in a one-off gig. He revolutionised drumming.
That's really sad about Dusty Hill. I know a lot of people will only really know them from their Eliminator / Afterburner and early MTV era (doubt those videos would have been made these days), but their 70s albums were their best. IMHO I thought Eliminator / Afterburner - and the use of synths - pushed them in the wrong direction for their following albums, but their last studio album La Futura was a real return to form.
