For tango, try to find some Daniel Melingo. This fellow has been heralded as the new voice of Argentine tango. He is both taking the tango back to its roots when it was created in the bordellos of La Boca as an ad campaign for prostitutes (vertical entertainment as prelude to horizontal) and putting a contemporary edgy dispair and growl to it that is bringing whole new generation of fans into the tango fold. He was described to me by a bunch of folks in Buenos Aires as "the guy who is putting the whorehouse back in the tango." I bought his first disk, "Tangos Bajos," in Argentina and it remains one of my all-time favorites. He has a new one out, too, but, try as I might, I haven't been able to track down a copy in the U.S. May have to get a friend down in BA to send me one. This stuff is definitely not Astor Piazollo nor in any way even vaguley sterilized or polite -- it's unapologetically raw (though very well produced) and, as far as I am concerned, unqualifiedly wonderful. My two cents.
