I don't care to get into analyzing tango to death which happens to be your main interest. I don't understand why you consider my comments to be spam.
I am not advertising the milongas in BsAs. That's where I dance.
You seem content to avoid exposure to tango's roots. That's your choice. You certainly have lots of learn about the culture of tango.
Rise and fall is a British invention by the creators of the International (or Standard) ballroom style used in competitions (Blackpool). What they call tango with all that head shaking bears no resemblance to the original. If you believe, Mr. Bailey, that tango needs a rise and fall, then by all means just do it. You are the authority.
Having started posting on this thread and I just can't resist commenting. If you don't care to analyse why are you here and why comment at all. People are learning, querying, seeking answers to all the contradictions that are Tango in all its various flavours. People sometimes open their mouths first (or commit to the keyboard) without first researching, people don't always listen and stick to their own beliefs, but that's life.
You keep recommending going to BsAs but most people cannot do that sensibly. A two week tango tourist trail holiday is not going to be all that enlightening or aid in absorbing Tango. That probably needs 3 months or more preferably and it takes time before Tango gets important enough to someone to even consider that, if it's possible at all.
I may criticise (silently in the main) show influenced tango, so-called tango for export or what one milonguero apparently recently called "European" Tango but the Argentinians themselves, their world touring shows and the teaching participants are to blame for the public's view that that is what is Tango. And it makes many people want to try dancing it.
In the end, if your rather dismissive view prevailed, you would not be witnessing the growth or at the least the continuation, of Tango. Dances always need new blood, it needs to be encouraged. Hopefully a few will proceed to discover the heart and soul of Tango but it takes time.
As for rise and fall being a British invention, I doubt that. The British Ballroom people do seem to be the first to codify it, set standards for it, teacher assessments and lesson syllabuses etc. But they did contrive Ballroom Tango from Argentine and unfortunately they didn't like what they considered the creepy hold. They (we) aren't latins. So they changed the visal leaning in to a modified ballroom leaning out hold.
They did not incorporate rise and fall, the ballroom version is as flat as possible, heel-lead and with bent legs in a mistaken effort to make it visually rather than physically grounded. To me it's all ugly in look and feel. Don't get me going on about all that leg-flicking head butting stuff which actually is another influence from another country altogether.
However DB is not talking about ballroom tango which you definitely are (Blackpool etc) and that's just confusing the issue.
