Original Broadway Cast. That and only that. The orchestrations, the tempos, the performances. All perfect. All 100% perfect.
Original London is essentially the same album, but with faster tempos and less elegance.
RNT has Dench and a decent Guittard and some fascinating orchestrations. Unfortunately, it also has Joanna Riding giving the 2nd most annoying Anne ever and a botched job of "Glamorous Life."
Soundtrack comes off as a castrated OBCR.
And the Revival, though complete, moves at a glacial pace with uninspired vocals and a music box for an orchestra, which isn't as charming as it sounds.
Just get the OBCR. You'll never need another recording.
