Singles, released digitally to the public as soon as they are completed is by far the best distribution strategy for indie artist's.
Music has become a free commodity and the quicker you can leverage this insight the better off your career will be..... because the live show is where you make your money.
Albums are merchandising methods which frankly, should be used as free give aways at live shows.
Remember, you are fighting for a slot on an iPod playlist.
You are fighting for relevancy online and in your region.
You are competing to be the first name that comes to mind when someone thinks about your niche.
Once you achieve this.....you'll get paid.
Wishing you continued success!
