I was looking at some discs at Chesky's site and they have a couple of free downloads from the Area 31 disc http://www.chesky.com/core/details.cfm?productcode=SACD288
. This disc is in David's personal top 10 list. One of the tracks available for free is "The Girl from Guatamala". He says,
Now let's listen to Track 4, "The Girl From Guatemala." This is my all-time reference for a female vocal. The soprano is about 10 feet behind the mike. You hear her delicate voice right in the center of the orchestra. This track is a great speaker crossover test as her voice should be seamless from the low to the high ranges. Here, should be a sense of coherency to the voice from octave to octave. There should not be any suck-outs or brightness in the frequency range."
These tracks won't give the sound of the disc but they are still pretty darn amazing!
