Jerry Williams Jr. (born July 12, 1942), generally credited under the pseudonym Swamp Dogg after 1970, is an American country soul and R&B singer, musician, songwriter and record producer.

[9][10] He released several more singles on Calla through to 1967, by now credited simply as Jerry Williams, but with little commercial success, although some of his records such as "If You Ask Me (Because I Love You)" later became staples of the Northern Soul movement in the UK.

"[12] Later in 1968 Williams began working as a producer at Atlantic Records with Jerry Wexler and Phil Walden,[2][13] on artists including Patti LaBelle & the Blue Belles, though he found the administration frustrating.

He coined the term "Swamp Music" for this awesome funk predominately played by all white musicians accompanying the R'n'B institutions e.g., Wilson Pickett, Aretha Franklin, King Curtis...

Commencing in 1970, I sung about sex, niggers, love, rednecks, war, peace, dead flies, home wreckers, Sly Stone, my daughters, politics, revolution and blood transfusions (just to name a few), and never got out of character.

Recording in Alabama and sincerely singing/writing about items that interested me, gave birth to the name Swamp Dogg.Having adopted his moniker before Snoop Dogg was born, he has claimed to be "the original D-O double G".

[15] In 1970, he emerged in his new Swamp Dogg persona, with two singles on Wally Roker's Canyon label, "Mama's Baby, Daddy's Maybe", again co-written with Bonds, and "Synthetic World".

Williams' new direction apparently followed an LSD trip, and was inspired by the radical politics of the time and by Frank Zappa's use of satire, while showing his own expertise in, and commitment to, deep soul and R&B music.

[2][16] Record critic Robert Christgau wrote that "Soul-seekers like myself are moderately mad for the obscure" album and has called it "legendary".

The sleeve showed him on the back of a giant white rat, and has frequently been ranked as one of the worst album covers of all time.

[2] In 1977 he had another minor R&B hit with "My Heart Just Can't Stop Dancing", credited to Swamp Dogg & the Riders of the New Funk.

[9] He continued to release albums through the 1970s and into the mid-1980s as Swamp Dogg, on various small independent labels and in a variety of styles including disco and country and maintained a healthy cult following.

Several other of his recordings were sampled, and in 2009 he released two new albums, Give Em as Little as You Can...As Often as You Have To...Or...A Tribute to Rock N Roll, and An Awful Christmas and a Lousy New Year.

[2] Swamp Dogg released a full-length album of new songs in 2014, The White Man Made Me Do It, which Williams described as being a sort of sequel to Total Destruction To Your Mind.
