Anyway, this is a split between two obviously extreme metal bands. You don't get a name like Hellcrawler in the pop music realm. Each band contributed about ten minutes worth of music, which does a surprisingly good job of introducing the band to someone like myself who is not familiar with either group.
Hellcrawler has taken the Entombed death 'n roll sound and run with it. The Slovenien group (that's right, Slovenian) has one full length album under their belt before this split. Their side of the split is three tracks of dirty, filthy death metal with some surprisingly catchy hooks. Third track "Green Machine" is a cover of one of the greatest Kyuss songs. They do a decent job putting their own spin on it.
Wölfe is definitely extreme. An odd mix of grindcore and blackened thrash. The band apparently does not actually name their songs, titling them with Roman numerals only. The production values leave a little to be desired as the sound is a little too high-pitched and grating. The drums have that certain St. Anger quality. The vocals are pretty terrible as well. I will likely not be revisiting Wölfe.
So, two sides, one really good and the other really bad. I will definitely be trying to track down some more Hellcrawler.
