Really nice tune! I love the harmony - specifically the inter-weaved borrowed chords that change the mood.
What really got me was the Dm(Maj7)-A-G-D thing. My ear went, "huh?" and then as it went on, it understood it (mMaj7/9s add alot of flavor) I expected IVs, but got minor IVs. Such a cadencial phrase is quite common in pop/rock/r&b. (ie: The Alicia Keys track - Brand New Me - F6-Fm6-C)
(Btw, Janet, AK may garner garner some inspiration since the piano is her signature instrument)
The vibes (were those vibes?) and pizzicato strings (and some kind bell) were really nice. Production wise, this sounded really good.
This piece was indeed "Pure and Simple." What inspired you to do this? Was it the Mrs.? (Perhaps, a duet may work on this track, too?)
