Since I started going to shows when I was about 15, I've always wondered why more bands didn't come around on tour more often. I live close to New Orleans, and Baton Rouge is a major city as well. My friends and I could never figure it out, and it was always something that upset us.
The older I get, the more I realize it's because not enough people support local music. Interviewing local Baton Rouge bands, photographing shows and actually "participating in the scene" for the past couple of years has really brought this to light. Even in New Orleans the local scene isn't what it could be. Venues close left and right, and the ones that are open don't want to take a chance on local bands. Sure singer songwriters have their chances at open mic nights, but full bands are left with few places to go.
Many of those who go to shows will easily spend $20-$100t o see a "major" touring band, but won't spend $5-$10 dollars to see multiple local bands play in one night. Their hesitation can be understood, because local shows can honestly be hit or miss. Someone would rather spend their money on a band they know they like than take a chance on a local act they're unsure of.
This, however, is where things get dicey. It's because people don't want to take a chance and spend those few dollars, or even show up for free shows, that venues don't exist or won't take chances. By paying that cover charge or even just showing up, you're showing those places that having shows is something that's important to you. You're essentially investing in your local music scene.
Going to shows and paying covers is only one part of supporting local music. Fans of local bands have to spread the word about their favorite hometown acts. Obviously social media is wonderful in this capacity, but never underestimate the power of good old fashioned word of mouth. Try suggesting a local band that's similar to their favorite "major" band. Bring your friends to a local show for your weekend night out. Small things like this are instrumental in getting a buzz going about your local scene.
Showing support in small ways opens so many doors for new things to happen. If helping out current local bands in ways like these works, it could inspire someone to start making music who never thought it was possible. More venues could start opening in cities where places to play are scarce. Music may not be a huge part of some people's lives, but to those who both love and play music, this type of support can mean the world.
