This could absolutely revolutionize the entire Williamsburg busking scene. Forever. Q TV now has a feature entitled "How To" With Q that features indie-bands and acts showing you how to play their songs on guitar. Thus far, the show has featured the likes of Vampire Weekend ("A Punk"), The National ("Fake Empire," "Slow Show"), Tegan & Sara ("Walking With A Ghost") and Sondre Lerche's bizarrely quirky 13-minute description of "To Be Surprised". The old dude near Union Square that covers "Landslide" every night is never going to know what hit him. Check out the "A Punk" video above, the video for "Fake Empire" and "Slow Show" below. Also: practice your scales, man.
