Pitchfork is an abbreviation for pitchforkmedia.com, which is an online magazine devoted mostly to coverage of independent music. The website, updated daily, centers upon 5 reviews of new albums, 4 to 6 newsposts, and 2 to 4 reviews of singles. While Pitchfork is known for its brutal honesty, it cannot properly be said that it isn't biased in a huge way. However, it is definite that Pitchfork is something that can be trusted for people with a taste for indie music.
I'm tripping shrooms, perhaps now would be a good time to go read Pitchfork for the first time.
