“Possible Impossible Dimension,” curated by Holly Myers, includes six artists who approach abstraction with a rigorous sense of spatial dynamics and an abiding concern for the relationship between the world they create in their work and the world outside their studio. The historical architecture of the landmark building in which the galleries are housed is effectively referenced by the artists, notably by Bari Ziperstein’s chandelier, and Dorsey Dunn’s sound work, which creates a poignant reflection on history (at Center for the Arts, Eagle Rock, Northeast Los Angeles).
