Styx is the "boundary" between the living and the dead.

Only the dead and buried can cross this river

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.

Styx is a kick ass 80's band that recorded such monster hits as "Renegade" and "Come Sail Away"; they are no where near the worst band ever, as that title belongs to those bitches known as REO Speedwagon.
Styx rules.
