Evolution of Songs

On some songs I worked for years. Here some examples how they developed.

The Song "The Strange one" on the album "unprofassional" became the song "Childhood" on the album "Gfuehlsweid".
1: First version 1999
2: Unprofassional album Version 2000
3: Live Version 2001
4: Gfuehlsweid Version 2005
The song "Brummer" on the album "unprofassional" evolved in a completely different song on the album "Gfuehlsweid".
1: Unprofassional Version 2000
2: Live Version 2000
3: Live Version 2001
4: Gfuehlsweid Version 2005
The evolution of the song "The Hug" is an example of negative evolution. I tried to technicaly improve the "unprofassional" version of the song but it lost the emotion.
1: First Version 1999
2: Unprofassional Version 2000
3: Live Version 2001.
4: Remix 2002
