Re-release of the 1988 album. These Germans released in 2009 their come-back album and now here is 'Power of Darkness'. They added 4 songs that were not on the 1988 issue (the last 4 tracks) and they did skip one that was on the 1988 album, I don't know why.
The album sounds retro indeed, back then the album and the band were not that popular and that won't change with this re-release. Necronomicon, Sadus and Kreator are bands you can compare them with. They just don't have the same skills or song-writing capacity. You can call it cult if you want.
Doesn't add a lot to today's market, just for fanatic collectors I would say.
