Yes, I've heard Monk's Epistrophy, probably a few versions. I have listened to that album by Ornette Coleman too.. It's actually the only one of his that I've checked out as it's regarded such as classic. Yoshihide's version's not for me, in part because there are sounds in there that remind me of my tinnitus
Summertime is such a popular standard. I like it, but it's not actually high on my list. I do think it's interesting how the song's musically quite sad while the lyrics seem positive. My current favorite is Billie Holiday's version, but again.. I like other songs more.
I actually wanted to watch Porgy and Bess one day, but I've yet to hunt down a version of it. This is a good reminder.
