I watch the HD performance on one of the HD-only type channels.. can't remember the name.. but they often miss instruments completely. I'll be watching some band playing away on a cello or bass and there is no sound of the instrument, at all. They even missed a lead guitar solo on one I watched. I was recording them to watch later in my big sound room but I stopped for this reason.
If the PBS recordings are good quality AND catch all the instruments, that's great news! I'll be sure to check them out. It's sad when I see such high-rez performances botched by bad production. Such is the way I've come to expect from the sucky music industry, though.
This gives me an idea for a new thread. Thanks!
