Nash Postponed: The premiere West Coast exhibition of photographs taken by singer-songwriter Graham Nash--a leading collector of photography--has been postponed until March because the artist was too busy working on the L.A. County Museum of Art exhibition “Selections From the Graham and Susan Nash Collection,” which opened Thursday. The show of Nash’s own portraits, produced with nontraditional printing techniques, was scheduled to open Dec. 15 at G. Ray Hawkins Gallery in Santa Monica.
