Mr. Koester’s Delmark Records and his Chicago record store were vital in preserving and promoting music the big labels tended to overlook.
Bob Koester, who founded the influential Chicago blues and jazz label Delmark Records and was also the proprietor of an equally influential record store where players and fans mingled as they sought out new and vintage sounds, died on Wednesday at a care center in Evanston, Ill., near his home in Chicago. He was 88. His wife, Sue Koester, said the cause was complications of a stroke. Mr. Koester was a pivotal figure in Chicago and beyond, releasing early efforts by Sun Ra, Anthony Braxton, Jimmy Dawkins, Magic Sam and numerous other jazz and blues musicians. He captured the sound of Chicago’s vibrant blues scene of the 1960s on records like “Hoodoo Man Blues,” a much admired album by the singer and harmonica player Junior Wells, featuring the guitarist Buddy Guy, that was recorded in 1965. “Bob told us, ‘Play me a record just like you played last night in the club,’” Mr. Guy recalled in a 2009 interview with The New York Times, and somehow he caught the electric feel of a live performance. In 2008 the record was named to the Grammy Hall of Fame. About the same time, Delmark was recording early examples of the avant-garde jazz being promulgated by the pianist Muhal Richard Abrams and other members of the Association for the Advancement of Creative Musicians, an organization formed in Chicago in 1965. The company’s recordings were not, generally, the kind that generated a lot of sales. “If he felt something was significant, he wasn’t going to think about whether it would sell,” Ms. Koester said by phone. “He wanted people to hear it and experience the significance.” As Howard Mandel, the jazz critic and author, put it in a phone interview: “He followed his own star. He was not at all interested in trends.” For decades Mr. Koester’s record store, the Jazz Record Mart, provided enough financial support to allow Delmark to make records that didn’t sell a lot of copies. The store was more than an outlet for Delmark’s artists; it was packed with all sorts of records, many of them from collections Mr. Koester bought or traded for. “The place was just an amazing crossroads of people,” said Mr. Mandel, who worked there for a time in the early 1970s. Music lovers would come looking for obscure records; tourists would come because of the store’s reputation; musicians would come to swap stories and ideas. “Shakey Walter Horton and Ransom Knowling would hang out there, and Sunnyland Slim and Homesick James were always dropping by,” the harmonica player and bandleader Charlie Musselwhite, who was a clerk at the store in the mid-1960s, told The Times in 2009, rattling off the names of some fellow blues musicians.
