Balkan

Balkan Records was a Chicago-based record label run by Slavko A. V. Hlad that produced Folk Music, Polka, and other ethnic recordings. They also produced custom records from clients' tapes.

The parent company, Balkan Music Co., also maintained its own recording studio and a full service music store that carried sheet music, musical instruments, and offered music lessons. Many of the company's recordings have been reissued on CD by Esoteric Sound.
