your reference dvd

Depends on what you are shooting for...ear candy or eye candy. Music videos are cool, but nothing is as jaw-dropping as an action movie with great sound effects. For a person to experience those sort of things for the first time is quite memorable for them. If you've got Blu-Ray and a processor that can decode the new hi-def codecs....you've got to show them an action movie that has a great screen image. It will be more impressive for a first-timer than a concert DVD every time.

I've seen Chicago-front row-center live, and the Chicago/EWF (Earth, Wind, & Fire) DVD played on my 110" screen with a rear projector and 7.1 sound, is BETTER than being there LIVE!

And I 2nd Zigonht's recommendation of James Taylor - Beacon Hill.

Good listening and Good L@@King too!

The series Planet Earth will take your breath away. They use
ultra high speed cameras to photograph.
As far as a music video,I think the Eagles Farewell Tour is great.

The theaters go for loud,but they can't compete for the quality of the sound.TBK had me on the edge of my seat,many turns.Thought it was going to end at several different times.I can see why that might have messed up Mr Ledger.
