I don't know if there is a harder worker in the business of show than Jack White. His Nashville based Third Man Records has become an empire, and King Jack makes sure to keep the masses fed; whether it's with one of his own various bands, or a collaboration with anyone from Alicia Keys to Insane Clown posse, or singles/records for other bands that White himself produces. Yesterday he released the first single off of <em>Blunderbuss</em>, his forthcoming solo album, the first since the breakup of the White Stripes. Check it out.
