She's not spectacular, but she's not bad. Her Act One finale was a shocker! I was literally getting up to run to the restroom - it was my 13th time seeing the show, I knew how it ended - and I stopped dead to experience what was coming out of her mouth.
Pia has a nice singing voice, but her character loses a lot of its natural when she's obviously putting on an American accent. (A problem I noticed in the London production particularly.)
Dancing-wise, I thought she was really pretty good. I did notice they added sound effects to I Can't Do It..., her idea? She did a very nice job with the Hot Honey Rag, and stands up well next to Charlotte, the best-danced Roxie by far.
Although she may be too refined for Velma, her dancing is first rate- Hot Honey Rag is superb-the girls are really together... and she and Charlotte seem to be having fun doin it...., the voice cannot be topped- and she is sexy- Brava!
