Here's a good dose of ferocious fastcore/powerviolence from Orange County, California's FISSURE. This band is an unrelenting force of frantic guitar work, thick bass tones, spastic drum abuse and harsh vocals. These guys construct blistering chaos with absolutely no room to breathe between tracks. On the flip side is Australia's SHACKLES, an unbelievably brutal onslaught of powerviolence and face-shredding grindcore. Deep distortions and heavy feedback flow over these massive riffs, dirty bass sounds and girthy howls with crushing delivery.
