There are relatively few songs that, when they come up on random, force me to listen to the entire associated album immediately. Only Shallow by My Bloody Valentine is one of those songs. That riff is simply ridiculous. Amorphous and interesting and ass-kicking and catchy all at the same time... who cares if you can't make out the vocals? That's kind of the shoegazer thing.
Forgive the laughable early 90s video.
