Chicago-based ensemble Mississippi Heat has gone through many personnel changes throughout the years, but has remained a staple of the Windy City's blues scene. Formed in 1991 by harpist Pierre Larocque, the ensemble group performs vintage Chicago blues, along with Larocque's contemporary blues compositions, and has continually welcomed a various roster of musicians and vocalists. Today, the band boasts such members as John Primer, Muddy Water's last guitarist, and local guitar legend Carl Weathersby. Since their first release in 1993, Mississippi Heat has performed throughout the world and has been the subject of various documentary features, notably for Radio-Canada and Europe's ARTE. With resident vocalist Inetta Visor, the group has recently released Hattiesburg Blues, in 2008.
