Believe me, I could have been *much* stronger! ;-) Maybe she's done better performances elsewhere, but the Cambridge one wasn't up to scratch in any way.

Re minimal vocal range - I don't think she moved out of one octave for the whole show. That's acceptable for a good, expressive singer, but she wasn't. Soft songs were fine, but her voice never went above MP in the whole performance, so everything ended up being a soft song, just a faster or slower soft song. No edge at all, in any song; basically no dynamics in her singing; and every song she just followed the main melody line throughout with no real variation, improvisation or expression. And to be honest, her voice at Cambridge actually didn't sound like it'd take being pushed hard if she did try - it didn't have the depth for it. Not what I'd expect from a jazz singer, especially one who's supposed to be that good. I expect more from a jazz singer than "easy listening", which was what we got.

Don't know what the session musicians on the CDs were like (I've not heard any of her CDs, although my wife's got a couple), but her backing band in Cambridge was definitely nothing to write home about.

By all means, do go and see her on her current tour if you're a fan. If she's better at your place, then maybe she was having a bad day in Cambridge. Maybe on a good day she could even redeem her choice of songs. But on a bad day she'd be like she was in Cambridge - and since she's now officially a best-selling artist, tickets to her gigs are not cheap. If you're not a great fan and desperate to see her, make your decision accordingly.
