The art in this gallery is different from most of others around this area, which mainly feature stuff like landscapes and wildlife. I don’t really know how to describe art or know any names for the genres. I guess I would call local painter Claassen's stuff “edgier” or “more hip.” In any case, the gallery is located on one of SLO’s busy commercial streets (Higuera) and ducking in for a look may open your eyes to a new favorite artist.
You should check out his website because I have provided only a vague description in this tip. There, you can see examples of his art and also find out which exhibition is currently being put on at the gallery.
