I just wrote this for something and it occurred to post it here too...
I swear the hardest part of being in a band isn't the years and years of learning the instrument, it's not the hours upon hours of writing and arranging and practicing the material, it's not the nights spent writing biogs and emailing and getting the schedules of each band member to match up, it's not the time spent away from family networking or travelling to and from gigs and carrying gear, it's not the two or three hour sets on an empty stomach or the rushed (or absent) sound checks with landlords asking you to 'turn the drums down', or watching the volume limiter kill your expensive amp every time someone flushes the loo, it's not even the drunk guy shouting 'oasis' in your face all night and trying to play your precious instrument.
It's getting those landlords and venues to simply answer the phone, or text, or email or return your call with a gig.
That's it. That's the single hardest part in my twenty years gigging experience!
What's yours fellow muso's?
