Truly historically, tart saisons are far more likely to resemble what were served on Belgian farms in the 1800s than a Dupont-style saison. I believe it was even common to blend fresh saison with a small portion of old lambic prior to serving.Since everyone else is just kind of being mean and uninformative:
Most classic saisons will present very little to no tartness, whatsoever. American brewers' tart saisons have become very popular in recent years, but most of them are quite atypical, at least historically. Stylistically, these tart saisons share a lot more in common with American Wild Ales than they do saisons, at least in a classic sense. Saison Dupont is about as classic and delicious as it gets, imo.
That said, crazy, crazy sour saisons are basically wild ales and are new to the world. Something like Saison Bernice, on the other hand, or any of the non-BA HF saisons, are probably fairy to style historically.
