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
128x128kray
Planty and Kraussy off the album 'Raising sand', track title
'Sister Rosetta goes before us', mesmerizing lilting track, lovely vocals by Kraussy, and all the instruments are nice with a special mention of the violin/fiddle in the background.
Lesse. 'The Wand of Youth', EMI, the track: 'the Wild Bears' for depth and soundstage.

For impact and ability to demonstrate energy without being overbearing: "Paranoid" by Black Sabbath, on white label Vertigo vinyl

for dynamic range vs detail: Verdi's Requiem, RCA Soria series, track 2 'Dies Irae' (LP only)

For outright beauty to make you cry: 'Heil dir, Sonne!' Seigfried, from the Decca/Solti Ring Cycle (LP), also 'The Lark Ascending' Vaughn Williams, EMI cond. by Boult (LP)

for a recording that sounds better and better, the better you stereo is, and sounds awful the worse it is: 'Village Music of Bulgaria' Nonesuch (LP)
