Last week, we released our picks for the 50 Most Important Metal Bands in the 21st Century. Each of those 50 bands represented a group of artists moving the needle forward for heavy metal. We covered as much ground as possible in the list, whether it be veterans of the craft solidifying their genre as an art form, to young upstarts introducing new ideas and concepts. Each band on the list strikes to the core of why heavy metal is an evolving and constantly progressive art form that doesn't lose site of its roots.

We took a deeper look at all the bands on the list, and broke them down into all the important elements: genres, country of origins, skulls on album covers -- the whole deal. Dig into our deep dive breakdown of the 50 Most Important Metal Bands in the 21st Century.
