Best song for immediate impact when presenting or testing?


I, as most of you, have my regular tunes that I play or listen to when trying out a new system or playing music for friends. My current starter is 'Feels like Rain' by Aaron Neville. It engages me immediately because I love it so, but it is also very well recorded and has a bass voice doing backup which in the right system has a real visceral impact.

I was at an Audio shop recently, listening to my standards, and wanted to show the sales consultant a piece that he might not have heard. I played 'Golden Rust' off the Miles Gurtu album. After about 30 seconds, he pulled out his device and added the song to his favorites. I asked why did he add so quickly, and he said that the opening electronica had a three dimensional stereophonic quality that made a remarkable impression right off the bat. I paraphrase lightly; that was his comment.

What pieces do you play of any genre that have an immediate impact, especially for people listening to a good system for the first time?

Return To Forever Returns, live show from 2009, cut 5, Song to the Pharaoh Kings.  This will test the limits of your speakers.  See if your passives, if you have them will survive.  Also a great test of your active woofers.  Cheers.
Thanks to all who joined this conversation in the spirit intended. I'll listen to all.

As mentioned, I usually start with Aaron Neville's Feels Like Rain. Next is Time After Time, Eva Cassidy. Taj Mahal: Queen Bee. Angelique Kidjo, Summertime. Girl From Ipanema, Getz Gilberto (this song played on a good system in 1995, brought me into hi quality systems). Then I take requests, and finish up with The End by the Beatles. If they're in the mood for something downbeat, You Want it Darker, by Leonard Cohen.

Fudai - shame.
