On this week’s episode of Arts & Seizures, host Mike Edison and friends discuss the Black Sabbath reunion, the merits of Guns N’ Roses, Lemmy’s recent passing, the “cacophonous mess” that was Lady Gaga’s tribute to David Bowie on the GRAMMYs, and _Louder Than Hell, _“the heaviest book on the planet.” They’re joined via phone by Kenny Aronoff, one of the world’s most influential and in-demand drummers.
