Blue Cheer (yeah this should be obvious, but I'm wondering what album I should start with)
NON are arguably the pinnacle of aggressive electronic music. I suggest a compilation of their more gripping material called Easy Listening For Iron Youth.
Also, their album God and Beast
is essential, especially the closing track.
Just start in chronological order for Blue Cheer! They manage to be both heavy and fun, like a slow Motorhead in that regard.
Speaking of fun, it's hard not to find The Mentors hilarious. Their music is obviously silly, but enjoyable in moderation. Their You Axed For It! & Up The Dose
double album is worth having around. Despite his eventually fatal alcoholism, El Duce was the finest troll that that world of daylight has ever seen.
