I don't know if thats defined what I'm looking for or if its different than what I'm looking for. I have an idea of what its about but I wanna be sure.
The one man band is an old thing that was kind of a novelty for entertainment. A person would be playing several instruments at the same time like drums, an accordian, a horned instrument and maybe something else. Not good music necessarily. May I suggest to you as good as you are with your acoustic guitar to get one of those harmonica holders that go around your neck and practice with it. I did that a few years ago and it works pretty well for me on a few of my songs.
a band consisting of one person. Classically it was one person playing several different instruments.
this is a one man band
