Although Sad Wings of Destiny wasn't a huge seller, it did land Judas Priest a major-label deal with Columbia, for whom they debuted with the fearlessly experimental Sin After Sin. Retaining the progressive elements of its predecessor, Sin After Sin upped the levels of instrumental technique and melody while incorporating a greater variety of influences. It's possible to hear touches of Jimi Hendrix, Queen, Led Zeppelin, Pink Floyd, and Southern rock, not to mention one of the most effective left-field cover choices in metal history on the Joan Baez tune "Diamonds and Rust" (which became a minor hit in England). As a result, it isn't the most metallic or musically cohesive Priest album, but overall, it's extremely close to the same level of brilliance as most of their '70s output. Every track is worthwhile, although "Sinner" and "Dissident Aggressor" (later covered by Slayer, a real testament to its heaviness) are two particular highlights
