My faves from this killer 'summarize-a-band in one sentence' thread on ILM:
Belle & Sebastian: "Och, the pencil sharpener's snapped the lead again. I guess I'll just have to colour her blouse in green instead.
The Ramones: "1, 2, 3, 4"
Tori Amos: "Mumbleglurgy. Stiletto. Purple money dishwasher. Meep meep."
Springsteen: in the heart of the cold steel city with nothing but a bag of dreams.
The best of all is the ode to Jeff Magnum (we kid because we love):
Neutral Milk Hotel: "Jesus cum sister two-chords"
I wish I was feeling witty enough to contribute, but my attempt at Cat Power ended up reading like bad 16-yr-old-girl-poetry.
