Light artist James Turrell will be on hand for the opening of “Gard Blue,” a new exhibition of his work at the Spencer Museum of Art, the museum announced Friday.

Turrell is planning a conversation-style public talk at 11 a.m. Sept. 15 in the auditorium at the museum, 1301 Mississippi St. Doors to the Central Court, where the exhibit will be located, will open at noon.

Turrell has been the talk of the art world this summer, with simultaneous retrospectives of his work on view at New York City’s Guggenheim museum, the Los Angeles County Museum of Art and the Museum of Fine Arts, Houston.

The headlining work of the Spencer’s Turrell exhibition is “Gard Blue” of 1968, featuring a projection of blue light inside a box-like room constructed inside the Central Court. Holograms Turrell created more recently will surround “Gard Blue,” highlighting the evolution of his vision.
