2009 two CD release. Cobra Records was founded in 1956 by Eli Toscano, a record shop owner in Chicago. He sensibly left all the creative decisions to his in-house producer and writer Willie Dixon, who had just left Chess Records. Dixon then signed the three best second generation performers of Chicago Blues: Buddy Guy, Otis Rush and Magic Sam. He wrote them some great songs and encouraged them to develop the single note guitar leads that distinguished their style.
