After their very successful second full-length, Chile’s best thrash band Ripper are back with their first new material in three years. Sensory Stagnation feels like a continuation and evolution of the band’s established sound. The high-speed thrashing and intricate riffs are still there, as well as the philosophical lyrics and incomprehensibly good bass work. But the band has leaned a little further into their progressive influences, with just a bit more Atheist riding shotgun with their usual Teutonic and South American thrash forerunners. The result is an outing that feels rich despite a runtime of only twenty minutes or so, loaded with some of the band’s best playing and most fascinating ideas to date.
