Nat Hentoff Remembers Charles Mingus.

Nat Hentoff writes about jazz and civil liberties, but describes his profession as "being a troublemaker." Hentoff began collecting jazz records and hanging out in jazz clubs as a young adult, and later hosted a jazz radio show and edited a magazine before co-founding the Jazz Review, a journal of criticism. Hentoff currently writes a column for the Village Voice and his subjects are often the First Amendment or civil liberties, and he is a staunch defender of free speech. His latest book, "Boston Boy," is a memoir about growing up in Chicago and Boston.

Sue Graham Mingus' new memoir Tonight at Noon is about her love affair with the late jazz musician and composer Charles Mingus. She is a former magazine editor and publisher, and now works as a music producer. She also created and directs repertory ensembles that carry on the music of her late husband. Tonight at Noon... Three or Four Shades of Love, a CD featuring tracks by the Mingus Big Band and the Charles Mingues Orchestra, was recently released on the Dreyfus Jazz Label.
