"Disturbing the Noise" is the 3rd full-length studio album by Brazilian thrash metal act Attomica. The album was released through Cogumelo Records in 1991. Attomica had temporarily been a four-piece on "Limits of Insanity (1989)", with bassist André Rod also taking on the vocal duties on that album, but on "Disturbing the Noise", Attomica are back in a five-piece constellation again. André Rod solely concentrates on playing bass on this album and new lead vocalist is Fábio Moreira. There´s been a change on the guitarist post too as João Márcio Francis has replaced Pyda Rod as the band´s second guitarist. Besides André Rod, guitarist João Paulo Francis and drummer Mário Sanefuji are the usual suspects in the lineup.
With a different lead vocalist on each of the band´s first three albums, Attomica naturally hadn´t settled on a sound that they could say was their own. The debut features a savage blackened old school thrash metal assault, while "Limits of Insanity (1989)" was a more technically oriented thrash metal album with a very high pitched and monotone vocal style on top. On "Disturbing the Noise" the sound has changed again, and this time around the music is reminiscent of the more aggressive and fast-paced 80s Slayer and especially mid-80s Dark Angel. It´s safe to say that by 1991 that wasn´t exactly the most original thing to play, but Attomica are convincing and deliver their music with both decent skill and passion.
New lead vocalist Fábio Moreira is a pretty standard raw type thrash metal singer with a staccato delivery. he is nothing out of the ordinary, but he gets the job done and compared to the monotone and brain meltingly high pitched vocals by André Rod, he is a 100% upgrade to Attomica´s music. The instrumental performances are raw, unpolished, and reasonably skillfully delivered. Pounding, fast, and powerful drumming, fast-paced thrashy riffing, and some blistering screaming atonal solos, are some of the ingredients in the band´s music. The sound production is raw and powerful and suits the band´s music perfectly.
After the rather weak "Limits of Insanity (1989)", I didn´t have high expectations to the quality of "Disturbing the Noise", but Attomica pull it off pretty great on this one, delivering a quality raw and aggressive thrash metal album and a 3.5 star (70%) rating is deserved.
