Very true. The last time I heard a whole tanda by a modern tango orchestra (and I mean pure tango by that, not fusion/neo/electro stuff, that tanda was by Sexteto Milonguero) here in NYC was about a year ago ( and I usually go to 2-3 milongas per week). It's a deplorable situation which sends a message to the musicians which goes like this: "No matter what you do, we are not going to play you, because you're not the real stuff." And if one raises the question one will get probably accused of not loving traditional tango music enough Well, I adore golden age tango music and I listen to it at home every day. That doesn't change my opinion that new orchestras should be given a chance though.
