I haven't heard the recording but I saw this production on Monday, and it's mesmerizing.
Imelda is probably the best Lovett I've ever seen, and if this production makes it's way across the pond she will be a force to be reckoned with. Her development of Lovett is different from many that we've seen before, and the costumes that they've put her in reflect that. She has an element of comedy, and not the broad comedy apparent in the Lansbury version (although fitting in that context). As everyone else has mentioned, her final scene with Sweeney in the grinding room is heartbreaking, and she throws herself into it.
Michael Ball is very good, but not my favorite interpretation of the role. That award goes to Michael Cerveris in the most recent Broadway production. He is in fine voice, and his character work is gripping, but he is over shadowed by Staunton for the majority of the evening.
The real star of this production is Jonathan Kent's direction. He perfectly blends the worlds of the productions which we seem to know the most about (The original cast and the Doyle Revival), so we have grand scale production, with dark and gore filled trauma.
John Bowe as the Judge also makes a very memorable turn. His 'Joanna' is perfectly jaw-dropping, and he is cleverly used in the staging of 'Poor Thing' to further the detest for his character.
REALLY hope this can transfer over to New York. Who cares if the last revival was only five years ago, if the show is good and people want to see it, why not bring it back if the production has the merits?
