Time is an essential aspect of Rogan’s work. His first major solo museum show, which included videos and sculptures, was held at the Berkeley Art Museum last year. Prior to that, in 2013, he showed work at Laurel Gitlen in New York. It is Altman Siegel, the San Francisco-based gallery who first showed the artist in 2010, that will present a selection of the artist’s portraits at FOG. Sourced from magazines, the works pay tribute to some of the unknown artists in the Northern California scene. They appear almost ghost-like, subtle, and mysterious—soft on color and heavy on the ephemeral.
