Tracks worth for a 1 Million system


Hi,

What people would play on an ultra high end systems?
Which tracks really justify to be played on such iconic concepts?

I could imagine piano concerts as one. 

Which track would you play if you had a "one opportunity" to make these myths (i.e. ultra high end speakers) come alive. 

There is no best here, there is no one to rule them all. Such music could come from a very rare genre or instrument. 
"... regardless of speaker/system/cable/room/region matching.." 

Let us hear what the world says.

Do you guys have any recommendations for great classical guitar? Ideally a recording that really brings out the instrument. Many of the "classics" I've listened to sound too much like they were recording the venue as much as the artist. 
@powermd not sure if you have had any recommendations yet but here are a few from my collection that should fit your needs

any of the Paul Galbraith Bach recordings, for example the Lute Suites on Delos. This should give you a nice sense of his style

LA Guitar Quartet "Dances from Renaissance to Nutcracker" also on Delos https://youtu.be/Fh1dKL6eJdY

and on Al Segno the Trio De Cologne "La Belle Excentrique", a little harder to sourcebut extracts here

@folkfreak 

Thank you for the suggestions. I look forward to testing them out.

My new speakers and amp arrived courtesy of an Audiogon seller- Dynaudio contour 3.4s and an ATI 3000 amp. The speakers need breaking in but so far I'm impressed. 
Modern guitar recordings are compressed to death.  Try the old Voxbox of Manuel Barrueco--it's called something like 300 (400?) years of Guitar.  This recording of his Ruck actually sounds like a guitar, and the playing is fantastic.  Check out the Albeniz and Granados selections especially.
The last time I put together a system from scratch I found classical guitar to be surprisingly easy to reproduce compared to voice, string quartet, full orchestra, etc.  So it would not be my first choice for a million-dollar system, FWIW.
