Rocka Rolla is the debut album by the British heavy metal group Judas Priest, released in 1974. It was produced by Rodger Bain, who had made a name for himself as the producer of Black Sabbath's first three albums. This album was played entirely "live" (i.e. all musicians playing simultaneously as in a concert, vs. the more popular method of each musician's parts being recorded separately and then mixing them).[info sheet from distr.]
