It's good; I like it. I transcribed the recording by Elis and Jobim, here, and found that my band, including me, couldn't play it, particularly the bridge when it gets off onto the up-beat and then back on to the down-beat. Jobim, I believe, commented that the tune was a "tone poem" but this recording is much more than that, IMO, it's a tone-poem song. Brilliance recorded, IMO.
