Probably Human are a progressive metal band from Ventura, California whose name tips the hand at a playfully cerebral sensibility beneath the heavy instrumentation. Formed in 2019, they navigate the intricate compositional territory of prog metal with a distinctly West Coast irreverence, layering complex arrangements with moments of genuine melodic weight.

Progtronic from Sunnyvale, California carry one of the more unusual trajectories in American metal — beginning in 1987 as a progressive electronic rock project before eventually arriving at technical death metal, a transformation that mirrors the genre's own evolution over those decades. That early experimental background likely informs the complexity and compositional ambition they bring to their technical death work, setting them apart from bands who grew up solely within extreme metal. Across nearly four decades of activity, they represent a rare continuity of artistic evolution within the underground.
