Only two tracks to test your system, forever!

So many choices with only two answers.......

Gregory Porter-Don't Be a Fool

Norman Brown-Missing You

It cannot be only two but here are two that I often choose.

Dire Straits - Calling Elvis

Cowboy Junkies - Crescent Moon

Out All Night, The Pietasters

Never Be, Mustard Plug

The best track to test any system comes from Tchaikovsky ’s Nutcracker Suite -- the pas de deux after they’ve come out of the forest. Incredible track. Most CDs have this directly mastered from digital:

Edit:. Also the real cannon typically used in his 1812 Overture is an absolute must.  The best recordings have warnings on the label that they can damage some systems.  That's the pinnacle right there

Billy Cobham - Stratus

Supertramp - School
