I just got the new Lines Ballet Blu-Ray from ArtHaus (via Amazon):
The video and audio quality are gorgeous, as you'd expect it to be since they filmed this in a studio specifically for DVD/BD release, as opposed to a live event. The camera angles are interesting, and work for the most part: the high overhead shots going down are a bit less successful than some of the dolly shots that pan across the stage (middle parts of Scheherazade). The opening scene of Triangle of the Squinches will be very, very challenging for any deinterlacer because of the fine elastic bands in the set. You will see shimmering at times, and when a dancer with darker skin steps in front of it, your video processor could go crazy on the edges.
The audio quality, available in 2-channel PCM or 5.1 DTS-HD Master, is really good with a wide bandwidth and good dynamics. Your subs will be working from more than just the footfalls on stage.
If you've seen Lines Ballet or Alonzo King's choreography before, you'll know what to expect. It is classically based movement with pointe shoes, turnout, and the shape aesthetics of ballet, but stretched and often distorted beyond classical lines. If you think of Frank Gehry's architectural style as it relates to classical Greek architecture, King's movement vocabulary has a similar relationship to classical ballet. The dancing is of course gorgeous, as are his dancers --- in the dance world, when you say "Lines dancer" to someone, they will know exactly what you mean, and this disk lets you see plenty of that. Music is quite varied as King likes to collaborate with composers, with original scores by Mickey Hart and Zakir Hussain, and more classical stuff by Corelli and Poulenc.
The lighting, set design, and costumes are also beautiful, and the camera work and direction really shows them off well. I can't even imagine how much it cost to put this together, much less how a small company like Lines raised the money to do this project. My favorite scene is the middle of Scheherazade where glowing cloth balloons descend on a couple (Laurel Keen and David Harvey) in the middle of a really intense duet. I love Keen's dancing, so that may have colored my perception a bit.
There is also a short documentary/interview with Alonzo King and a few of his dancers. It's OK, but not as in-depth as it could be, as it tends to repeat certain things too often.
Anyway, it's definitely worth a rental (because you may not like the choreography), but it's worth considering owning too, if for nothing else than the beautiful production quality lavished on the BD.
