Styx
(3 of 7)
This American prog-rock band sailed through the ’70s and ’80s with hits like “Mr. Roboto” and “Come Sail Away,” but if they were sailing on the mythical river Styx, they would have to be dead. In classical Greek mythology Styx is a river in the underworld over which the souls of the dead are ferried. The word is a cognate of the Greek stygos meaning “hatred” and stygnos meaning “gloomy.”
