The hardest part about being in a band is being in a band.
Writing songs, no problem. Getting gigs, no problem.
Getting the bassist to show up for practice at all let alone on time, freaking impossible.
Getting the lead guitarist to stop shredding between songs so we can discuss what we want to play/work on next, freaking impossible.
Getting sensitive whiny musicians to not take every suggestion about composition or tone as a personal insult meant to disparage their musical talent and them as a person, freaking impossible.
