The following is taken completely from : The Red Saunders Research Foundation (The Chess Label Part II (1953-1955))
The end of 1955 marks a watershed in Chess history. Up to this point the label had been strictly a singles operation, like nearly all of the smaller independents. The 33 1/3 rpm LP had become enough of a commercial force by this time, however, that the Chess brothers were now preparing to enter that market (they were apparently never tempted during the days of 10-inch LPs).
For their first 12-inch microgroove release, originally on Marterry, they turned to the singer who had saved the label commercially back in 1951. (The name change to Argo took place so quickly that the Marterry LP is quite rare.) The Al Hibbler LP (matrix numbers 7881A for Side A, 7881B for Side B) was a straight reissue of the five Chess singles that had featured him. "Feather Roll Blues," an instrumental by Billy Strayhorn and band from Hibbler's first session for Sunrise, was included in the LP because it had been the flip side of Chess 1457. There was additional material from Sunrise and Miracle in the Chess vaults, but none of it was used on this occasion. Argo also released a 45-rpm EP consisting of four of the Hibbler items.
