Sour revelation

Tried Abbaye De Saint Bon-Chien today at a local spot that was having a sour tap takeover. I was fairly blown away, suffice it to say. Never had a beer quite like that, with sour, funky elements perfectly in balance, great complexity, a beer that really appeals to my wine geek side.
So, I am wondering if there are other similar beers that the Board might recommend, preferably ones that are not excruciatingly hard to find?

where are you located?

I basically posted the exact same thing last year!

Let’s see, since then, I’ve had a few Rodenbach that I’ve liked, Cantillon esp the kriek, and all the rare barrels if you can find someone to buy em off.
