You should have a good song and a well produced recording of the music at this point. Now we need to wrap it up and present it to the world. This is where your creative ideas can come to life. Get a few good photographs of yourself that exemplify the attitude and image that you want to associate with your music. This is really half of the success of your music and career in the music industry. You need to be able to captivate the listener and get them to feel the emotion that is embedded in the music. Record labels and movie producers will take you seriously if you appear to believe in your own music, so you need to create an image that they can market with the music.
You don't have to go way over the top like Lady Gaga or Marilyn Manson, but it is very obvious that they succeeded in the music industry because their music was good and they had an image that captivated people's attention. I don't think either of them would have been such a success story if they took photos in jeans and t-shirt hanging out in their backyard. Now you don't have to get crazy with the editing in Photoshop, but I'd suggest that you hire a professional photographer and get some shots that have good lighting and are framed with an interesting background. Black and white photos are always classy and have a sense of professionalism to them. That's why so many band photos are black and white that accompany a press kit.
Once you have a few good photos, you need to get some sort of web presence. You can get a free band account on many different websites. I'd highly recommend one that offers licensing opportunities. There are a bunch to choose from, but I'd suggest starting with sonicbids.com or musicclout.com. Both of these sites allow you to upload music and create an artist profile. If you have about $10 to spare per month, I'd highly recommend you build your own website and have control over the design and look of your online presence. You can easily build your own custom site with squarespace.com or wix.com for about $10/mo. Check out some of the websites built by our studio clients: The New Position & Justin Fawsitt. Both of these sites were constructed by the musicians and only took a few moments to setup and publish live on the web.
This is a step that you cannot afford to overlook. You need to believe in your music and developing your image will be the foundation for the career you are going to build. Just as you got feedback from your friends and family for your music, you should also get feedback on your image. If you want to accelerate your career, hire a producer that has experience in developing musicians in the public eye.
