Okay, let's put chemistry aside. We all know that most good bands have great musical chemistry and personalities clash. So put the personalities aside and pick your fantasy band. I'll even be nice for those of us who like multiple people and say you can have an alternate at each instrument.
Lead singer: Sebastian Bach and maybe Axl as a backup
Lead Guitar: Slash with Joe Perry as the backup
Rhythm guitar: Mick Marrs
Bass guitar: Nikki Sixx with Flea as the backup
Drums: Tommy Lee might make Rikki Rocket the backup
I guess it's obvious where my musical influence is and what I love to listen to.
