I enjoyed the vocals and the song.
I never became accustomed to the electronic drums... I'm assuming that it was a creative choice. I think that if I was going to use electronic drums for this track that I'd go even further and make it sound like beat box drums, but I kept imagining a acoustic, maybe even a jazz kit, mixed in the background would sound appropriate.
In the absence of a killer solo, I can't really figure out what the sax was doing there. This song can sound complete with just piano, bass, and drums, but I also imagined how you might use a small horn section (trio) as a rich harmonic pad. If you use a section there is, perhaps, less expectation for a sax solo.
I really like the song.
I also think a live played bass line could effectively frame you vocals and emphasize your personal sense of groove.
It was nice to hear singing where the vocals complimented the choice of song, song key, genre, etc. It seemed like you were at ease and enjoying the performance.
Thanks for sharing!
