Need song identified!

First off, hi! I'm new here. I basically searched for a place like this out of desperation. I've been driving myself crazy trying to find out who sings this song! Its hard to identify any of the words to the song but part of the song is played on this YouTube video. Unfortunately, the creator of the video does not say who preforms the song!

If anyone can help me out I would really, REALLY appreciate it!

Thanks in advance.

It appears to be "Acid Food" by Mogwai. It's right on the same page .
