Hmm. That's a weird mix. Lots to love, lots not to like. Federico has some nice music but not much that is good for dancing. Pontier? Alex Krebs? ?
Tracks for one tanda are sufficient, for example a few milongas from Alex Krebs.
But let's go through something like this realistically.
A quite attractive dance partner asks me to listen to Pontier/Sosa:
Okay, I understand, she asks me to create a tanda with that stuff and dance it with her.
And then I see on a report from my previous DJ set that I didn't play Tanturi.
So I'll listen to a typical track, Tanturi/Castillo:
Okay, that's how Tanturi sounds like, and I don't like Castillo's nasal voice anyway.
Ultimately I have to choose one or the other.
After the DJ set, the feedback came: "Great, there wasn't a single superfluous tanda!"
