Reddit mentions of Nine Inch Nails Live - Beside You in Time [Blu-ray]

Unfortunately, metal bands haven't really broken into the Blu-Ray market as far as I know. However, if you need something to watch, the Nine Inch Nails - Beside You in Time Blu-Ray is an amazing show.

Edit: I should also point out that it's not Blu-Ray, but the new Meshuggah DVD is DISGUSTINGLY AWESOME

• Blue Man Group - How to be a Megastar Live! -- the mixing is absolutely incredibly. the song at 6 minutes in that starts with the Blue Men joking around on the PVC pipes, the moment the band comes in at once gives me chills. Their DVD Audio releases are also amazing. The Audio DVD-A is my go-to showcase for my theater.

iRobot is a personal favorie. Anything from Disney/Pixar (especially Wall E) is amazing. Kung Fu Panda does a great job. if you are into the bands, the Nine Inch Nails "Beside You in Time" Blu Ray is gorgeous as well as Metallica's "Francais Pour Une Nuit"

everyone that i listed will also give your surround sound a solid work out if you have it set up
