Episode No. 382 of The Modern Art Notes Podcast features artist Allen Ruppersberg and curator Lucinda Barnes.

The Hammer Museum is presenting “Allen Ruppersberg: Intellectual Property, 1968-2018.” The exhibition is a retrospective that reveals Ruppersberg’s pioneering role in the development of conceptual art and how he has advanced his ideas into painting, collage and installation in the decades since. It includes extensive presentation of both of Ruppersberg’s most important and groundbreaking projects: Al’s Cafe (1969), in which Ruppersberg created a cafe and served customers artist-made meals that included ingredients such as rocks and pine cones; and Al’s Grand Hotel (1971), a fully functioning hotel (named after a 1932 MGM movie) with artist-designed rooms. The exhibition was curated by Siri Engberg with assistance from curatorial fellows Jordan Carter and Fabián Leyva-Barragán, and debuted at the Walker Art Center in Minneapolis. It is on view at the Hammer through May 12. The exhibition catalogue was published by the Walker. Amazon offers it for $41.

On the second segment, Lucinda Barnes discusses “Hans Hofmann: The Nature of Abstraction,” a broad survey of Hofmann’s painting from 1930 through the end of his life in 1966. The exhibition is at the Berkeley Art Museum through July 21, when it will travel to the Peabody Essex Museum in Salem, Mass. Hofmann was a German-born painter and teacher whose came to the United States in 1930, when he was 50 years old, to teach and to continue his career. The exhibition’s excellent catalogue was published by University of California Press. Amazon offers it for $48.
