I became a fan of this type of music through Diana Krall, but that's okay I'm not that old. So here's the deal, I want to hear the way the old greats did these songs so that I can better understand and hopefully appreciate the new versions. The problem is that i don't want to buy CDs and then find out that the recordings are terrible. I don't expect them to be on the same level as a modern recording of high fidelity, but I want the best available. Sinatra and Cole are the two artists I'm most interested in, but anything else in thsi direction is welcome.
