I'm having trouble matching any of these demos with Helmet/Page songs aside from Throwing Punches. It doesn't help that the track titles on the YouTube video don't match the order (or quantity) of what's in the audio.

There are eight tracks in that video - the second one, starting at about 4:30, is Throwing Punches.

Anyone want to take stabs at which of these tracks appear when in the YouTube timeline?

Enemies
Sleep
L.A. Water
Low Expectations
Crashing Foreign Cars

Without vocals, it's always difficult to establish provenance on stuff like this.
