A tonal inflection suffered by male singers influenced by the vocal style of Pearl Jams' Eddie Vedder.
The effect is a mildly scowling, muffled, "out the side of the mouth" sounding vocal with long dramatic notes favored. Sufferers seem to be seeking a overtly masculine sound.
Famous effected artists: Scott Weiland, John Butler, Xavier Rudd, Chris Cornell, Scott Stapp.
Yeah, the song writing is pretty good, but the lead singer has a severe case of The Eddies.
