There are occasions when we are tested by some albums. Some Metal/Rock genres have strange features that can make us feel animosity in the beginning, but giving them more chances, the truth will become clear. So, we can state that the Sludge/Doom Metal quartet POSEIDON, from UK, is really on a dangerous path with their first album, "Prologue," and it's a dangerous way for them.

Although some experimental parts (even some clean guitars and melodic voices) can be heard, as on "Mother Mary; Son of Scorn," all this nasty and raw sound is truly boring sometimes. The use of such long songs is truly a problem if you don't have enough rhythmic changes to make the fan pay attention to what you are playing. No, their work is not bad at all, but such long times could be expressed in songs with 4-5 minutes. The sound quality is another great problem. Ok, I truly know that Sludge Metal has a dirty and raw form to be, but not as excessive as here. It's too raw, too smokey and greasy, what make our understanding of what they are about difficult. It's not about a dirty sonority, but about to be understood without a great effort, and they failed in this point.

Some good ideas can be heard on "The Beginning; the End, the Colony" (there are pretty good arrangements on this song), "Mother Mary; Son of Scorn" (the clean moments on its end are very good, with some experimental insight, but the preceding dirty ones are really annoying), "Chainbreaker" (the vocals on its cleaner and progressive moments are very good, but the sound quality doesn't help) and "Omega" (another one with charm experimental moments, but the dirty atmosphere erodes their efforts). We can hear that they are talented musicians, that the band has future. Maybe a good producer could help them to reach what they really can do.
