After I heard Kat's debut album, 666, I knew that this band had something going for themselves. So I checked out this, their second album, and was a bit disappointed.
This is certainly thrash, but much better recorded and played with a high degree of professionalism. The riffs have more chug to them, more of a composed feel and a lot of bottom end. It's a bit like Testament, but much better than anything they released in later years, and certainly a lot fucking heavier, but way too controlled and compressed.
"Diabelski Dom Cz. 2" is a very strong song, following in the tradition of the other two parts of this song (found on the debut), and has some nice churning riffs and quality soloing from Piotr Luczak. "Glos z Ciemnoci" is slow, nearly balladesque, but not the emasculated numbers from the thrash bands turned glam. The ending of "Œpisz jak kamieñ" has a clever little clean outro with a tasteful solo, which works really well.
Roman's vocals are still great on here, but do suffer from being over produced. His clean vocals are pretty good though, but I would have preferred more evil sounding shit.
The best comparison I have is to Metallica's Master of Puppets. The riffs are stong, the playing is very competent, but in becoming better musicians, the harshness has been reduced quite a bit. This still feels evil, but perhaps the Diet Coke of evil. Kat's charm lay in making raw, evil thrash with a lot of speed, which is sadly absent here. Bottom line: strong, but not outstanding, especially alongside 666.
