Love your reviews - just commented on the Groundhog Day review yesterday. Why no reviews of music disks? This isn't labeled as a movie-only area. There's a rising tide of music-oriented disks coming out to take advantage of the lossless audio on BD, both old concert films and new ones.
For pure video and sound quality, the Legends of Jazz Showcase disk, with highlights of that PBS live in studio series shot in HD, has some of the best video and audio around, as well as some of the best musical content as well. It's my go-to disk to show off my theater. I'm putting together a music BD collection, and there's a growing amount of content every day.
