Record collector, record store owner, producer, Bob Koester left St.Louis in 1958 moved to Chicago and purchased Seymour's Jazz Mart to rename it Jazz Record Mart, making it Chicago's premier Jazz and Blues record store. After different locations in the city, Koester was in charge from 1958 to 2018. In the basement of Jazz Record Mart that same 1958 Koester founded Delmar Records, the most decisive label together with Chess Records in the history of blues music, to which  joined Alligator Records in the 1970s. Delmar finally became Delmark and more than five hundred albums have been released under its production and among its many essentials the albums of Magic Sam, Junior Wells, Luther Allison, Mighty Joe Young, JB Hutto, Carey Bell and son Lurrie Bell have been iconic recordings for the Chicago blues in the sixties and seventies. Beyond the celebration that all blues fans around the world join in, the uninterrupted 70 years of Delmark Records highlights the vitality of this genre and the loyalty of untold numbers of blues music lovers. At present, Delmark Records albums continue to mark a line of homogeneity and avant-garde characteristics of the label throughout these years, offering its faithful public as much quality as warmth. Congrats guys!
