please update this band

Queens death-thrash outfit Charnel House drew from New York's fertile extreme metal soil, combining the aggression of early thrash with the morbid textures of death metal. Their approach reflects the raw intensity that defined the New York underground in the genre's formative years.

Formed by drummer Richard Christy and featuring a rotating cast of established heavy metal figures, New York's Charred Walls of the Damned fuses melodic power metal with thrash-inflected intensity and a polished, technically accomplished sound. The project channels the high-energy songwriting sensibility that Christy honed during his years behind the kit in Death and Iced Earth.

Long Island's Chemical Warfare channels the raw energy of NWOBHM-influenced speed and thrash metal with an East Coast bite. The band keeps their attack lean and fast, rooted in the early underground tape-trading era.

Rochester progressive/thrash outfit Circular Ruins constructs labyrinthine compositions that balance intricate technicality with driving groove. Named after the Borges story, they favor cerebral complexity over brute force.
