This song is really simple, which is just as well as it's my first tab. It's a pain that you can't find Gorillaz tabs.
This is pretty much exactly it, but I'm not completely sure about the second(I think it's D#) power chord.

e|---------------------
B|---------------------
G|-----6-6-6-----------
D|-5-5-6-6-4-5-5/88-8/5
A|-5-5-4-4-4-5-5/88-8/5
E|-3-3-------3-3/66-6/3

This is main riff, it's more or less all in the song, but I'll update soon. The timing is different for the A# powerchord and I tried my best to represent it, and don't forget the slide
