These are not exaclty super groups, but they would go well together:
- Guitar- David Gilmour
- Drums- Dave Grohl
- Bass- Geezer Butler
- Vocals and piano- Steven Wilson
which would sort of be an agressive, early heavy metal influenced space rock band
-or-
- Guitar- Tony Iommi (Black Sabbath)
- Drums- Will Champion (Coldplay)
- Bass- Roger Waters (Pink Floyd)
- Vocals, lyrics- Mikael Åkerfeldt (Opeth) & Win Butler (Arcade Fire)
- Keyboard- Richard Wright (Pink Floyd)
which would be sort of a loud mix of art rock and post-rock taking influences from jazz and blues
-or-
A band composed of dead people only:
- Jim Morrison- Vocals, lyrics
- Kurt Cobain- Vocals, guitars, lyrics
- John Bonham- Drums
- Cliff Burton- Bass
This would be better than my living super groups. It would be jazz, prog, blues and heavily acid influenced grunge/ hard rock and have insane instrumental pieces and genius lyrics.
