John Primer (born March 5, 1945, Camden, Mississippi, United States) is an American Chicago blues and electric blues singer and guitarist who played behind Junior Wells in the house band at Theresa's Lounge and as a member of the bands of Willie Dixon, Muddy Waters and Magic Slim before launching an award-winning career as a front man, carrying forward the traditional Windy City sound into the 21st century.

He eventually started learning his trade by playing for tips at the legendary Maxwell Street market alongside blues superstars and raw beginners like himself.

The band eventually started booking gigs in small bars and clubs on the city's West Side, most prominently The Bow Tie, Lover's Lounge and The Place.

In 1968, he left Rushing to join the soul/R&B group, The Brotherhood Band, where he served as front man and began developing the unique singing style he is known for today.

After seeing him in action at Theresa's, Willie Dixon invited Primer to join his Chicago Blues All-Stars in 1979, touring with him internationally for a year, during which he honed his skills as a slide guitarist, vocalist and songwriter.

Primer held the position until Waters' passing in 1983, during which he received additional training on the six-string and Muddy instilled in him the importance of maintaining the old-school blues tradition.

[citation needed] Primer has subsequently enjoyed an enduring relationship with Wolf Records as well as his own Blues House Productions imprint, which was founded in 2008.
