Originally recorded in Chicago by the Swedish Broadcasting Corporation, this release comes from a radio broadcast of these recordings.  A British blues enthusiast  taped them off the radio at a different speed & harp players for years were mystified by the keys of the harps. Only when the Swedish Blues Society released them under the title BLUESKVARTER was the mystery solved. (we still have copies of the BLUESKVARTER CDS available- check the title in the search box)...............
