Concert Review: Cult Leader @ Union Transfer - Philadelphia, PA 11/15/16

I've never heard Cult Leader before November 15th. I beg the pardon of Cult Leader and their following for my ignorance of the genre they represent. I'm going to open this post to the possibility for discussion on this genre (Metal Core, Grind Core, Death Metal) and similar genres. You can all thank Cult Leader for this opportunity to discuss.  I've heard the YouTube personality Tempo talk about the subtlety of the vocals and guitar sound that define these differences. I always thought it all sounded the same and was really kind of boring. My first exposure to the ultra grinding sound was a band called Death from the 80's. Blazing fast, demonic sounding vocals, intensity but who gives a shit when it all sounds the same!!! I've been curious about the subtlety but remembering what Death sounded like I never could drum up the patience to investigate. This night I would get my chance ready or not!!!
