This has happened seven years ago but even Wikipedia only noticed it in 2018.
Personally, I only noticed it today.
Ruth White (1925 – 2013) was an American composer noted for her work in early electronic music.
Of interest to me is her 1969 Baudelaire album, on which she reads 10 poems from The Flowers of Evil. This is really bizarre and reading her liner notes makes the experience only weirder. “The Litanies of Satan” is one of the poems that got him in to trouble.
Somehow his death did not appear on my radar back in 2013. These however: Junior Murvin, Lou Reed, JJ Cale, Bobby Bland, Ray Manzarek, Vincent Montana, Jr., Kevin Ayers, Donald Byrd and Cecil Womack, did.
