Before Elvis made Jerry Leiber and Mike Stoller wealthy rock and roll tunesmiths, the record hustlers tried running an R&B indie label of their own. They got the idea of writing, arranging, producing and releasing songs by new artists on their Spark Records imprint after being screwed over by Don Robey for the royalties from Big Mama Thornton's original hit version of Hound Dog. Although their major discovery was the Robins (later the Coasters) -- whose raunchy swingers Riot In Cell Block #9, The Hatchet Man, Whadaya Want? and Smokey Joe's Cafe are highlights here -- they also cut a load of joyously greasy groovers by largely forgotten flakes like Ray Agee, Big Boy Groves, Garland the Great and some hard-shouting badass discovered by Ike Turner known as the Sly Fox. A small but important piece of the rock and roll puzzle.
