Here's a little background of what I do:
1. I busk in the subways here in NYC, singing and using background tracks with a mic a small amp. It's been great for my development as a singer, brings in income, pays for voice lessons, and gets a few people on my fan list. I am considering bringing my keyboard and portable power into the subway from time to time (did it in the past) so that will really ramp up my act. I am gradually replacing the karaoke tracks I use with my own recordings of piano accompaniment. The NEW YORK TIMES published an autobiographical account of my life as a musician recently, which can be found here:

2. I sing and play for hire at weddings and special events.
3. I produce my own small concerts, singing and playing.
4. I do a bit of church work as a singer and want to do more.
5. Eventually, my goal is to gradually phase out my day job in an office, and phase in enough gigs that I can support myself as a musician.
