Here are some Blu-rays that I use for reference discs, both audio and video.
Heart Live in Seattle, label is Image Entertainment. This concert is one of the rare 5.0 only DTS HD Master but believe me, it lacks no bass.
Rush Snakes and Arrows, label Anthem Entertainment. 5.1 DTS HD Master. Spectacular audio and video if you are a Rush fan.
Stevie Nicks Live, label Soundstage, 5.1 uncompressed PCM, awesome sound and video, good mix of Stevies's solo stuff and Fleetwood Mac favorites.
If any of the above artists appeal to you, I highly recommend you check these out.
