Would you be the guitarist, lead singer, bassist or drummer? Or something else? And if you wouldn't be lead singer, would you sing backup? If you were lead singer, would you play an instrument as well?
I'd be backup singer/rhythm guitarist. I can sing really well, but my my voice isn't distinctive enough to sing lead. And I have a great sense of rhythm when playing guitar. :3
What would your band be called?
Adjective Noun! Or, something following that format. And completely random.
What time of music would your band play? Compare it to other groups or artists you like.
Pop-rock. Something Paramore-Cartel-Sugarcult-ish (Palm Trees and Power Lines era). Throw that all in a blender. A female voice, of course. >> Because, in my opinion, female backups on male voices sound a little odd.
Would your band play in huge stadiums or in small clubs? Would you have all the members wear costumes, or just whatever?
Small clubs. >> Stadiums would scare the crap out of me.
Costumes? Heavens, no. Then Halloween would have no purpose! Halloween is for playing shows in costume!
