Matthew Collings is the reason I started exploring more and more modern and contemporary art. Ever since my high school AP Art History class, where I alone (and the professor) defended Abstract Expressionism and Dada while everyone else was cheering on the Renaissance, I knew that I was, for whatever reason, attracted to the conceptual. Because of Matthew Collings's 'This is Modern Art' video series, I took the leap and learned more. If it wasn't for him, I don't think I'd be exposed to AT LEAST half of the artists I know and love now.
I hope to meet him someday to say thanks in person. :)
