Hello Rightly
The vocal delivery is not a style that I particularly enjoy, but as you say, you have achieved what you wanted, and I can here the "quiet confidence" for sure. So the fact that it is not my "thing" vocals wise, is irrelevant.
What I really do like, is the brass instrumentation, which carries the song along really, really well. Perhaps the drums could have done with a little more variation.
Good stuff, well done
Bill
