If I recall correctly, I stayed away from most Rock... In the sense that I didn't load up on screamin' guitars or heavy drum sets, or Robert Plant type vocals.
I took 5 tracks for my primary cuts... anything beyond that was icing on the cake:
I took a Jazz cut, Evolution from Joe Lovano's From The Soul.
I used Stravinsky's Le Sacre du Printemps, starting with the last 30 seconds of the Introduction through roughly the first minute of Spring Round Dance... about 6 minutes of this Ballet, performed by MTT and the Boston Symphony Orchestra.
Fiona Apple, Paper Bag from When the Pawn...
Love Letter, Nick Cave and the Bad Seeds, No More Shall We Part (and if needed, Tori Amos' Northern Lad, From the Choir Girl Hotel)
Lou Reed, Egg Cream, from Set The Twilight Reeling
Each of these were picked because I not only new them well, but to expose flaws in the speakers.
Saxophone, Bass, Piano, and drums. No amplification. Exceptional production.
6 minutes of orchestral music that goes from solo instrument to full orchestra and back to quietude... ranging from strong percussion hits and significant variance in passages exposing different tone and timbre.
Fioana's vocals over the building instrumentation
Nick cave to expose if the male vocal got "chesty." And his Piano. The strings up high and the bass line help stretch the sound a bit... do they stay in balance, do the strings get "whiny?" (Tori's Piano work is a little more broad and dynamic... her vocals push into a range that can come across as strident. Yes there's still bass and drums, but I found that it doesn't get in the way here, in fact, some of her Bosie overlaps the bass line which is nice to hear how the two sounds balance out in the reproduction.)
Lou Reed: I love Lou's Guitar work, and the sounds he creates. Egg Cream is such a dense layer of great overdriven guitar sound with the band and his vocals... My personal tribute to my love of rock, and to make certain the speakers I chose could make some noise.
A couple Bonus cuts: Gravediggaz, Twelve Jewelz, a RZA cut that bumps, but it's all about his vocals, the articulation and clarity of which are all important.
And my nod to trully manufactured music: Gorillaz, 19/2000 [Jungle Fresh] from Laika Come Home. This was all about the Bass. Can the speaker survive?
