We're getting right back into semantics again. I would rather just agree to disagree since this is very clearly something which we not all agree on. Some people feel very uncomfortable calling it Argentine Tango unless it is something very specific, thats why we end up with so many classifications in music and dance. Others, myself included, could really care less what its called. Lets worry more about the pleasure in our own dances than about the sanctity of everyone elses. Also is there anything else I might like if I like Piazzolla? I like things like Otros Aires and Gotan Project too, but I already have that experimental stuff and I am now looking for newer interpetations of more old fashioned recordings. I absolutely love Piazzolla's Zero Hour, picked up Hector del Curtos Eternal Tango and loved it, and two other things by Quintango and the Silencio Tango Orchestra which I liked a bit too. Any other suggestions or maybe I should ask this in a new post.
