Best tracks to "show off" your system


I know there are certain songs that seem to bring out your system better than others.

which songs to you put on to show off your system to friends?

for me:
1. My love is - Diana Krall
2. Girl from Impanema - Getz/Gilberto
kray
Gordon Goodwin's Big Phat Band "Sing, Sang, Sung" from the CD "Swingin' for the Fences". Everyone who's heard this track on my system has asked for the name of the artist and CD...and many have bought the disc.

"Waves:The Bossa Nova Sessions". I started my vinyl collection in 1958 and this double album (one disc is 45RPM) may be the best sounding non-classical record in my stable.
Lkc boot - What Sheffield Lab site? www.sheffieldlab.com says "This domain is expired". Is there another one?
FIM Audiophile Reference IV offers a nice mix of well recorded, musically enjoyable titles.
Wstritt, I believe Sheffield is relocating and perhaps that why their page is down. http://www.regnar.com/Sheffield%20Recordings.htm (last CD on the list) indicates that one should still be able to order it. I guess I'll have to wait and see.

Since I am here...another favorite demo CD is Lorena McKennit (sp) Book of Secrets. I use the third song, but they are all exceptional.
