The Majorie Barrick Museum is fluid about a lot of things, especially how many exhibits it’s showing at any given time -- sometimes it’s one mega-show and a smaller display, sometimes it’s six different presentations. For about six more months, the city’s main contemporary art museum is going with three. Contemporary Ex-Votos -- the de facto headliner show -- pairs traditional Mexican art with works that broadly celebrate LatinX culture; In Relation combines pieces from the Barrick collection with new ones created by local artists to expand the notion of motherhood; and P0RTAL diversifies the hat trick with a showcase devoted to graphic design. As usual for the Barrick, lots of art -- and lots of variety.
