Striker
Much as it will leave me open to ridicule, I have to say I like Tool.I'm not familiar with their catalogue, but if this song is typical of their writing style, then they're almost the opposite of prog rock - they have one idea for a riff and play it for the entire duration of the song with no progression at all...
That said, the song almost sounds like the intro to a prog rock song, though. If they used almost exactly what they have there with maybe a few minor variations for the start of a 10 minute song that then went on to have peaks and troughs and take you on more of a musical journey then it would qualify.
Take this Tool song for example... They start off with only a few basic ideas with variations on the theme, but they pass it between instruments a bit and vary it more and more throughout the song while incorporating other themes, very much like you see in classical music.
I'm surprised you don't know of The Fall. As Peel once said - 'always different, always the same' (or something along those lines).
