Genre-bending greats

Swamp Dogg (real name Jerry Williams Jr) is a well-known black American singer, songwriter, producer and Williams Jr's alter ego. A few years back, I wrote about Blame It On The Dogg: The Swamp Dogg Anthology 1968-1978, which features some of his hit R&B songs (put out under his real name and alter ego), such as She's A Heartbreaker by Gene Pitney and Stop Knocking by Ruth Brown.
