It took me a few hearings to warm up to it, but yes, I'd recommend it. It takes careful listening to understand the entire plot if you haven't seen the show, so listen to it when you have the time to take it all in. Many people think this is ALW's best score since Phantom, and I tend to agree with them. Some of it is derivative, but there is some solid writing here, too, such as "All For Laura". The performances, especially Maria Friedman's, are excellent, though whether you prefer Michael Ball or Michael Crawford in the Fosco role is a matter of taste. However, it is Crawford on the recording.
