Well, you oughtta. In another 10 years, the Pixies will be as revered as the Velvet Underground, and you'll need to know this stuff to retain your cachet once facial piercings are finally, mercifully played out. You'll need to know that "Wave of Mutilation (UK Surf)" and its ascending bubble-chain of silvery guitar notes from the ocean's floor preceded Radiohead's austere Kid A by 11 years, and not the other way around. You will need to be capable of casually mentioning that the steady, burning drums and incandescent guitar shrieks of "Into the White" predated the Foo Fighters' "Everlong." You'll need to know that the Pixies covered Neil Young ("I've Been Waiting for You" and "Winterlong") years before Pearl Jam made it fashionable to do so. You'll need to know that before grunge came along and depressed everyone, there was guitar rock that was loud and fast and fun. Come back, Pixies -- we miss you.
