"Breaking the Law" was off the groundbreaking 1980 LP, British Steel, which is regarded as one of the most important hard rock albums of the 1980's. While 1981's Point of Entry is a solid album, it does suffer by comparison, if only because British Steel is just that good. However, the high points remain quite strong; in short, this is some of the best 1980's hard rock ever made.
The anthemic "Hot Rockin'" (no "g") is representative of this period, and is just a great hard rock song. On the downside, some critics believed that in focusing on straight up songs the band lost some of the darkness and mystique the their fanbase loved, something that Judas Priest rectified on the superb Screaming for Vengeance album in 1982.
The video starts as a workout tape, with the band exercising (and doing about as well as one would expect from a metal band). Apparently, leather pants sans shirts constituted metal workout wear in 1981. We then see the band showering (unclear if they are still in their leather pants) and blow drying, before an extremely poorly lit (and shot) car scene. Finally, we get to see the band perform, complete with fire.
Judas Priest remained popular throughout the 1980's and remains together (with some personnel changes along the way) as of this writing.
