Lyric discussion by Lampens 

Cover art for Killing Floor lyrics by Jimi Hendrix Experience, The

Killing floor is a slaughterhouse. A crappy job black people could have during the forties in Chicago. Howlin Wolf who wrote it maybe had some slaughterhouse crappy job in the beginning. I believe Skip James had a song that references it too. The dude is crying cause his wife has left him and he also got a real crappy job working at the slaughterhouse. That's enough to make a grown man cry I guess lol.
