Sin After Sin is often received with mixed emotions. Firstly, it isn't a commercial music product at all, which makes it fascinating. A masterpiece to be slowly digested. This album is one of Priest's most intriguing, yet brilliant productions. It touches many musical ranges... it is heavy (ie. the Sinner), brutally heavy (Dissident Aggresor), furious (Call for the Priest), soft and moody (Last Rose of Summer), atmospheric and soulful (Here Come the Tears), et all. Rob Halford's vocals and lyrics are at their peak here. Glenn and KK's guitars are imaginative, skillful and impressive. Ian Hill's bass is... mmmh, let's better skip that with Simon Phillip's incredible drumming!! Until this day I still can't believe some of the prodigious and intricate drums parts he laid down for those sessions (sadly, he only acted as a session player). Simon started a whole thrashy drum movement with his dexterity in Sin After Sin. Roger Glover's production here is frequently critized for not achieving a heavier sound, but I disagree with that, as the end result is just what was needed musically. The real beauty of Sin After Sin is that one can actually listen to many new subtle things each time one listens to it, no matter how many times played back... and that simply doesn't happen often these days. IT HAS MAGIC ALL OVER IT. This is a must item in any rock CD collection. A timeless classic!
