I've always liked songs that start completely different then how they end.
For example, metal music that starts with classical music, acoustic guitars, or piano, then morphs into sweeping arpeggios or heavy electric guitar chords.
Kind of like this.
The founding members of Savatage actually went on to start Trans-Siberian Orchestra.
Anyway, what are some songs that you enjoy that begin in one style, and end in another? (Any Genre)
