Episode No. 198 of The Modern Art Notes Podcast features author Nancy Princenthal and artist David Maisel.

Princenthal is the author of “Agnes Martin: Her Life and Art,” which was just published by Thames and Hudson. It is the first biography of the artist and comes as Martin is undergoing a significant examination: Earlier this year the Tate premiered a Martin retrospective, an exhibition that will travel to New York and Los Angeles, and next spring University of California Press will publish Christina Bryan Rosenberger’s “Drawing the Line: The Early Work of Agnes Martin.” Princenthal is a former senior editor at the magazine Art in America. Amazon offers the book for $26.

On the second segment, we revisit a 2013 conversation between host Tyler Green and artist David Maisel. The HBO series “True Detective” wrapped up its second season earlier this month. The program featured Maisel’s work in its opening sequence. Maisel came onto the program on the occasion of Steidl’s publishing a Maisel monograph titled “Black Maps.” Amazon offers it for $40.
