I've given it a couple of listens so far and I'm not impressed. People are talking about how it compares to the classic albums of the 70's, 80's and 90's but never mind that, in comparison to 'Angel of Retribution', this is still a disappointing record.
To me 'Angel of Retribution' was what I'd describe as a good album but not great. Definitely not at the quality of 'Painkiller', 'Screaming for Vengeance', 'Defenders of the Faith' etc but good enough to show the band still had plenty to offer and that getting Halford back and making more Music was worth it.
On that basis, the new album doesn't deliver. Many have criticised the sound production of it but I actually think it sounds good, it's the songs themselves that are lacklustre. Nothing really stands out, nothing really gets you thinking "this would be good to hear live" or anything like that and some songs are just boring. The album just gives you absolutely no immediate reason to listen to it over most of their other records, other than repeated listens in the hope that something about the album will grab you.
