Her first album for Reprise, Love, was recorded for RCA but not released by them..something to do with it being uncommercial or something. Sinatra bought the tapes from them when he signed Clooney and then released it himself. AFAIC, it's her masterpiece, and one of Riddle's as well, one of a handful.
The one after, that, Thanks For Nothing is a very mixed bag, but there's some good stuff on it. It's not as deep as Love, though, but to be fair, very little in that realm was/is.
Other than that, I know she did some Reprise Repertoire Company (or whatever it was called) performances, and I don't know what, if anything, else. Singles, maybe? She was heading downhill that whole time.
Here's my two favorites from the Thanks...album, fwiw:
Wounded Bird reissued it a few years ago, and I bought it. To be honest, those two are the only cuts of it I'd go out of my way to ever buy again.
But Love, oh my goodness...
