This is a fantastic video. This piece sounds triumphant and proud. Suggestions of works from this composer, if you dont mind?
The Scythian Suite is a great place to start for anyone remotely interested in metal, and is admittedly the reason why I began paying more attention to classical in the first place.
The name of the particular movement in that video is "The Pagan God and the Dance of the Evil Spirits", part of the Scythian Suite. Prokofiev is somewhat influenced by Igor Stravinsky; there's clear similarities between that composition and the Rites of Spring, or in, at least, how imposing they both wanted to be.
I also liked his Symphony No. 5.
