"Gutter Ballet", which was released in 1989, has been considered the band's true turning point. Since that album, the band has adopted a more progressive style, writing longer songs with more complex melodies and differing vocal styles, rather than the more straightforward power metal style that was apparent in earlier works. The change to a more progressive, operatic style was also precipitated by Jon, after seeing a performance of "Phantom of the Opera" in Toronto. The songs "Gutter Ballet" and "When the Crowds Are Gone" are examples of this influence from that album, as was the next Savatage's release (which even included "Opera" in its title). Again, two videos were made for the songs "When the Crowds Are Gone" and "Gutter Ballet" which received airplay on MTV.
