First of all, do not settle when it comes to band members!
Too many bands just find the next guy who can play the instrument they need and sign them up as the new, permanent band member. I cannot stress this enough, but take the time to find members that you really click with. And I’m talking relationally. If you guys can jam together without a hitch and create great sounding music, that’s cool, but if you can’t hang out together for twenty minutes without getting sick of each other, (even if it’s only a little) it’s best if you part ways. One day you’ll be in the studio twelve hours a day for three months straight with that person, and then it’ll really hit the fan.
