The Flesh Eaters were an amazing band, born of the LA punk scene back when punk meant aggressively different, not just blandly aggressive. Their first few albums are pure gold; this song is from "Forever Came Today", released on band leader Chris D.'s own Ruby Records in 1982.
This album has never been reissued on CD, and the original vinyl is somewhat rare. (I paid $45 for my copy this year.) Still, if you look around the web with a vigilant eye, you can probably find a download of it here or there. (Maybe try Googling "the flesh eaters forever came today mp3" or something.) This, along with "A Minute To Pray A Second To Die" (Ruby Records, 1981) are essential listening for anyone even halfway interested in this sort of thing...
The video for this song may be a little trite, but I love it anyway.
