The Thrones is Joe Preston, formerly of the Melvins, though I believe they are still technically together. Known to some as "logger punk" and to others as "earth metal", it is as unique an experience as one can expect from a huge guy with a double necked guitar and a beat box. IMHO, his bass playing is better than his guitar playing, sounding a bit like godheadsilo. Joe, ironically, denies being in "the thrones".

See also Caspar Brotzmann Massacre, for this sorta guitar.
