This doesn’t sound like a live album at all. In fact, going in blind, all I could think of was that this was one of those “fake” live albums which are recorded in a studio. It seems I was half-correct, with the vocals being re-recorded at a later date. To be honest, they should have just scrapped the whole thing if it came to this, but whatever, live albums don’t exactly have a history of being transparent and honest with the music consumer.
As for the material? Well, it’s classic Priest 70s stuff, of course, captured as the band were finding their stride in more straightforward songwriting. An interesting document of course, especially in light of the whole vocal situation, but one that I could only really recommend to completionists. There is no reason for a new fan of Judas Priest to be listening to this thing.
