The Art 21 Series serves as a great resource for artists, educators, and students. I really appreciate how they categorize each artist's work by themes such as power, place, and identity. This becomes really useful when trying to address larger concepts, particularly for art lesson plans. The 15 min interview videos of each artist provide insightful first-hand information about the artist's work, but they can also be misguiding and almost function as a turn-off. After viewing some of the videos, a type of friction developed between my prior aadmiration and thoughts about certain works and the manner in which some of these artists discuss their work.
