I often talk to musicians who are stalling in putting their songs or albums out because they don’t think the material will be heard by enough people. Or, they are afraid that upon release they’ll have to take the project to a big time level. Perhaps they think doing something cool is enough, but they feel they’ll be judged by others, for you know, not becoming “successful” with their work.
As a side note, success is relative and personal. If you start a project and stay on course to finish it, that is already a level of success.
But, in regards to the above, it’s a mental trap. The truth is that not every band’s goal is to be the biggest band in the world. There are numerous one or two member groups that put out great music out there through the internet for the sake of being creative. Many of them don’t even play shows.
There is nothing wrong with starting a band to take on the world and become the next Metallica and there is nothing wrong with releasing an EP for the sake of getting the songs out of your head and into the universe. You can set your own goals for success and follow them as much as you care to. Your songs, your band, your life. That’s enough.
Some of my favorite bands never became “big” or mostly went under the radar. There is coolness in being the underdog, too.
