1.) Join an already established band, the project of a well-known lead singer. Said singer was once a member of a famous band, but left due to "artistic differences". This option has good connections and a higher chance of success.
2.) Continue trying to push the band you're currently in. These guys are your friends and you've been playing with them for years. And as it stands now, you have more say in the creative direction and management of the band than you would in option one.
Which do you choose?
