A big problem is that a good chunk of Roger's fanbase is Pink Floyd fans who aren't into such things as opera (myself included). As far as Ca Ira is concerned I enjoyed listening to it once so far but I haven't been quite inclined to pop it back in my player since. It does have a nice 5.1 mix that is very generously well done. There's one bit on Disc 1 Track 10 that really scared the crap of out me (literaly) when a gunshot kicked out of NOWHERE in the rears and panned right up to the fronts so quickly I swore for a few seconds that it blown out all my speakers.
