oops. Sorry. I guess after I read your comment I kind of heard the drums in my head.
In all honesty, when I was done listening I flashed on the idea that it is sort of tamed down, old timey, Jefferson Airplane thing going on and drums were part of that imagined impression.
The vocals seem beautiful but perhaps emotionally displaced from the vibe of the guitar part.
I never heard the PJHarvey version but I am guessing it's a bit edgier or rev'ed up in feel.
I think I was imagining a bit more edge or drive to serve as a foil to the sweetness of the vocal delivery.
I'm way past my comfort level of commenting on someone else's art. I like to live and let live and try to avoid making suggestions like
you should add drums. I wish I'd understood the circumstance better beforehand and I didn't put my foot in my mouth, but I figured I should explain it now that I have. :-)
I'm going to change my mind and say I like it just the way it is for what it is. :-) Bring it on!
all the best,
mike
