I need 4, but that’s because one of my hobbies is being in a 5 piece band. I need the other 4 people to carry my untalented ass and I can’t be in a band with folks I’m not friends with. They like me because due to my obsession with being on time and prepared we get called back for gigs and booking agents (or sound guys, honestly) recommend us as local openers for large acts because we never let them down.
