It took me several listens to gather the full effect of what Adams was trying to accomplish on this opera/musical. I'm not sure that this recording fully harnesses it all, but it is an excellent recording.
As most people know, the recording is based on the 1994 major earthquake in California, and the structure of the recording reflects this, as movements 2-14 are meant as either solos or duets to reflect points of view. These pieces are sandwiched by ensemble numbers (part 1 and 15) that show off some of Adams' minimalist leanings but quickly switch over to pop and jazz sensibilities.
At moments, it's difficult to follow the flow of the action, especially on those parts that have no dialogue to connect sections. I suppose that is a nit-pickey point, all in all, but it was a noticable flaw as i heard it.
With Adams conducting, the cd shows off a different side of Adams. No, he's no Lloyd-Webber or Sondheim (thankfully) but the performance IS an interesting melding of opera and musical. While this concept, in my opinion, pales in comparison to his other operatic works, the work is a confident one, and is well worth listening to.
