As I understand it, Dennis DeYoung was more of a theatre guy. He's the one that went full-out on the Mr. Roboto album and tour. His idea was to have an album where all the songs told a story with a concert to go with it. He wanted all the flash of a big production, more or less at the expense of the music itself. The tour was a bit of a flop and it was around this time, if memory serves, that Dennis left the group. He tried to take the name "Styx" with him and there was a bit of a battle over that. The other members of the band, though, won out.
