Things were never going to be quite the same after this album. The weak Turbo and mediocre Ram It Down were to follow before the mighty Painkiller resurrected the band's sound. So this is a jewel of an album.
As others have said it is stylistically similar to Screaming For Vengeance but man is it a whole lot heavier. At a time when there was a lot of froth and bluster in rock music; DOTF as a metal album with balls. The opener, Freewheel Burning is thrash-a-la-Priest, and if my memory serves me correctly was released as a single (with a truly hammy video). Just listen to and try to keep up with Rob on the "Look before you leap..." refrain. Jawbreaker is now the stuff of legend and although a fantastic song is not the best thing on here. That title, for me, is between Rock Hard and The Sentinel. Love Bites is another of those dark, sexually themed songs that wouldn't have been out of place on Killing Machine whilst Eat Me Alive had the US moral majority up in arms at the time. Some Heads Are Gonna Roll and Night Comes Down are pure class which leads us to Heavy Duty which does exactly what it says on the tin - it's a Heavy Duty number with the singalong Defenders Of The Faith tagged on at the end.
Sure, some of the lyrics are poor and the album cover has to be one of the worst Priest ever released but overall it's a damn good album. I prefer SFV personally as there is a bit more diversity and a bit more light and shade on there whereas DOTF is heavy, heavy, heavy. A great album, buy it and KEEP THE FAITH!!!
