I was talking with a former guitar player who is still a good friend about our band days when we were young and stupid. We know so much now that would have made life back then so much easier, but there was no one to tell us any better - and no internet forums like this to learn from. Not that we would have listened anyway...To get to the point, what do you know now and would like to tell your younger self way back when? I've got a few easy ones: 1. Rehearsal space/setup We never had enough space to set up like you would on a stage (straight across), so we ended up playing in a circle, facing inward - with our amps behind us - firing away at our own ankles and straight at the guy across from us. What a clusterfudge. No wonder we couldn't hear ourselves, resulting in the dreaded Volume Wars...I would tell myself to tilt those freaking amps back like monitors and save everybody from the head-splitting volume. 2. Turn the f&*k down and/or get smaller amps! Related to #1. We probably needed about half the volume we used, but nooooo...Rock stars are cool 'cuz they're deaf! Closing out the hearing trilogy, we have... 3. Tell the drummer he doesn't have to beat his kit like John Bonham all the time. The rest of us have volume knobs, you don't. Ease up, O Mighty Thunderer. 4. Some people will not change their essential nature. Move on. If a guy is a selfish, combative bandmate, he's probably that way with other people in his life. If he won't change for people he's known all his life, what makes you think he'll change just because he's in your band? Life's too short and there are too many other musicians out there. Find one that's a decent human being. 5. Agree on a list of new songs to learn before you start practicing. "Do you know this one?" "No, how about this song..." You get the idea. Make out a list of 20 songs with each person choosing 5 (We were in a 4 piece band), so there's no hurt feelings ("We never play what I like!"), and make sure everybody has audio copies of all songs. Learn 4 songs each week, choosing 1 from each person's 5. Start a new list when the 20 are done. This solves many problems: What are we going to play? I've never heard that, how does it go? We never play my stuff! What are we practicing for next time? How about you guys? Pass on some knowledge!
