UMUR "Attomica" is the self-titled debut full-length studio album by Brazilian thrash metal act Attomica. The album was released through Equinox Discos in 1987. It was reissued and remastered on CD by Kill Again Records in 2006. The reissue features four bonues tracks.

The music on the album is filthy, raw and energetic thrash metal. Because of the high pitched snarling vocals I´ll even dare call this a blackened thrash metal release. The sound production is pretty lo-fi, noisy and distorted and it would be a stretch to call it professional sounding. It does however suit the extremely raw nature of the music very well. Other than "Lost Time" which is an instrumental track, the rest of the 7 tracks on the 37:00 minutes long album, are all aggressive blackened thrash metal tracks, delivered with fierce conviction and sometimes in a very fast pace too. It might not technically be blast beats, but considering that this album was released in 1987, the drumming is occasionally pretty fast-paced.

So if you like them as raw as they come, "Attomica" might by your poison. The musicianship could have been on a higher level, the sound production could certainly have sounded more professional and the songwriting is at times not of the highest quality either, but damn this album still possesses a rare "raw to the bone" type charm... a 3 star (60%) rating is warranted.
