Larry, really good that you've taken the time to record and post. Really brave, something I'm not ready to do yet. Pity I missed the other thread.
Good job on all three. I get the feeling you're almost there (certainly a lot closer than me), but are bogging down on details - instead of taking yourself outside the mechanics of playing and listening to yourself from the audience. On Corcovoda it seems as if you're trying hardest - and missing the most. Maybe put the music away for a while, also the backing track - and concentrate on playing it as you hear it - in other words play it in your head a few times, concentrating on how you want people to hear it - how it moves you - get it right in your head and then pick the sax up and play it that way. The notes/intonation will be there - cos it' s a part of what's in your head. When you're happy with that, repeat it with the backing track.
For me the definitive version of this is Stan Getz/Astrud Gilberto. And Stan's playing is an amazing contrast to her singing. She's subtle, clear and expressive - and his sax playing dances around her singing.... It's like he's making love to her as she sings... I'm not saying copy them, but rather hear the different ways they express the music, internalise it - then bring it out in your playing.
Good luck, lots of potential there!
