So this guitar prodigy, Sungha Jung, locked himself in his room for 60 hours after a fight with his mother and learned Nirvana's "Smells Like Teen Spirit." He didn't just learn it. He puts an interesting, haunting spin on it. I get in a fight with my mother? I just eat a whole bag of potato chips and drink too much scotch. I guess that's what separates mere mortals like myself from 11-year-old guitar prodigies.
