Hal Singer was an American R&B and jazz bandleader and saxophonist. He was the last surviving male survivor of the Tulsa race massacre.
He is known for such instrumentals as “Malcolm X” on the album Paris Soul Food (1969), produced by Bernard Estardy.
If you are a melomaniac, I’d check the latter’s “Ombilic Contact” en “Cha Tatch Ka”.
Bonnie Pointer was an American singer, part of the The Pointer Sisters.
The Pointer Sisters also did background vocals on “God Make Me Funky” (1975) by The Headhunters, the American jazz-funk fusion band led by Herbie Hancock.
I discovered Edwin Birdsong when I discovered Salsoul and have yet to listen to his earlier work for Polydor, Bamboo and Philadelphia International.
