Melbourne natives Mason have been in the spotlight the last few years. They were chosen by Annihilator's mainman Jeff Waters to tour with the band last year and this past summer. Waters' went on to say that Mason will kick his band's ass if they don't start practicing more. 'Impervious' sees Mason as a tightly wound thrash act. Tons of solos erupt from the twin-guitar attack, built to precision with one of the best production jobs I've heard in a long time. Vocally it is clean and aggressive with tracks that stimulate effective chorus sections. Mason is a cleverly defined, precise thrash metal band that rivals underground sensations like Game Over and Havok.
