Abco was a small label, in operation just from February through August 1956.
It was jointly owned by Joe Brown of JOB Records and Eli Toscano of A. B.'s One Stop; the company was housed in Toscano's premises at 2854 Roosevelt Road, while Joe Brown's Lawn Music handled the publishing. All ABCOs were recorded at Universal, with high-quality sonic results.
On July 11, Abco recorded four different artists, including bluesman Otis Rush, but by August, Abco had broken up.
Abco ended up responsible for just 9 releases, but these are nearly all top-quality music of the period.
