US progressive/technical death metal Xenosis have been at it for years, honing their craft with each album and showcasing a flair for experimentation too. On their fifth full-length album, "Hermetic Transmutation", they retain their core sound as they elaborate on both the progressive and technical aspects, even borrowing elements of brutal death metal and dissonant death metal to achieve that. The influences are finely integrated into their ever throbbing, busy music, never seeming forced and instead adding meaningful variation to their intense sound. The music's persistent groove belies its highly intricate quality; there's just so much happening while you're busy bobbing your head, tapping your feet, or rolling on the floor. After years of toiling, Xenosis have created a delightfully engrossing album that is bound to confound, tantalize, and ultimately satiate fans of this kind of music.
