Solo bluesman John Egan sings in a tone that suggests someone is constantly walking over his grave, and his lyrics are loaded with bad mojo like nature gone haywire and apocalyptic visions. All he needs live is his National Resonator, one of those shiny silver guitars that sting and snarl. Egan does things with a Resonator guitar that have to be illegal in less progressive states. Egan competed in the International Blues Challenge in Memphis in 2013, where he advanced to the semifinal round of 28 -- meaning that by that reckoning, Egan is one of the Top 30 solo bluesmen in the world. "Perhaps I was too edgy for the finals?" Egan quipped on Facebook. "All in all it was a great trip and a lot of fun."
