Styx is the river which forms the boundary between Earth and the Underworld, according to Greek mythology.
Styx is the "boundary" between the living and the dead.

1. A progrssive rock band that specialized in power ballads and reigned from the early 70's to the early 80's. Rather than the just the 80's. Similar sounding (but far superior) to REO Speedwagon.

2. A rivr mentioned in the book of Genisis and Greek legend.
proformers of such cult classics as "Mr. Roboto" and "The Grand Illusion."

A band that kicks ass! Especially with Lorelei and COME SAIL AWAY!
Styx is righteous, psychadelic, and amazingly flandiferous.

One of the greatest American rock bands ever formed. With a long active career that lasted from the early 70s to the mid 80s, Styx scored numerous hits such as "The Grand Illusion", "Blue Collar Man", "Pieces of Eight", "Babe", "Fooling Yourself (The Angry Young Man)", "Too Much Time On My Hands", and "Love Is The Ritual".
As other people have mentioned on here, Styx does have a similar sound to REO Speedwagon. That is because they play related forms of rock music, and they are both from Illinois, which explains the identical-sounding vocals.
Julian: Sonny also tawght me that Styx is one of thuh gweatest Amewican wock bands evor..."

1. One of the greatest rock bands of the 80's. Which means one of the best ever because new music sucks!

2. Caught a bad rep because critics are cynnical assholes!
Performed such classics as - Renegade, Come Sail Away, Rockin in Paradise, Mr. Roboto.

Much-maligned rock group, a guilty pleasure if ever there was one. One of their best albums, The Grand Illusion, is a loose concept album which takes the pursuit of fame as its theme and is best known for the anthemic 'Come Sail Away'.
"The Grand Illusion by Styx is an amazing album, and I'm not going to apologise for saying that."
