Relentless Mutation is a wonderous expression of speed, agility, heaviness, and catchiness all at once. The guitars shred, the drumming will make your head spin, and even the bass player makes his presence known in a big way throughout the duration of the album. Perhaps even more important to consider are the shifting textures and expert pacing that help this LP come together as a whole. Jazz, neoclassical, old school tech death, and progressive metal all play a part in making one of the most consistently engaging 30 minutes I have heard this year.
