This week's tanda is an spirited, mixed orchestra milonga set. Mixing orchestras is more common in milonga and vals tandas than it is in tango tandas. For one thing, some orchestras recorded very few milongas and/or valses, so it might be difficult to find 3 or 4 songs that fit cohesively together.
This is a set for the serious milonga dancers. Some dancers might be legitimately challenged by the tempo of these three milongas. I would believe that most dancers should be able to dance well to these if they just do two things, keep it simple and take smaller steps. If you do thse two simple things and the leader and follower are in synch then you should be able to have a nice, unrushed dance.
