Warning: free jazz, music's most loathed genre. I'd think it would be good for clearing Alzheimer's-related amyloid plaque, but my early-onset-dementia-addled wife would definitely not agree. Then again, she didn't ever like this stuff. Well, hell, I thought Led Zep was far worse noise than this stuff. Still do. Mostly because of Robert Plant. Yeah, I know he turned into something else.
