Just over a year ago, I decided that relying on other people in order to make music was more hassle than it was worth, so I picked up my acoustic and just started singing along to songs in my range.

I performed a few open mics, got lots of positive feedback, and just kept singing... in the shower, in my car, whenever.

I'm not even remotely close to being Sebastian Bach or Pavarotti, but it works for blues. :-)
