Giuseppe Panza di Biumo, interviewed by Christopher Knight in 1985 for the Archives of American Art:
DR. PANZA: Well, the connection between Abstract Expressionism and Pop Art was made through Rauschenberg, because if you look at Rauschenberg, you see also the sign of the painting. We don't see only the collage, also the object, the real object. And for this reason, it was natural for me to arrive at the Pop Art. However, when the Rauschenbergs came into my house there was some people which was very interested, but very few, but some was very fascinated by the work by Rothko and Kline, and Tapies, and to see this kind of art so different, so vulgar, made with the objects which are really found by upsetting the container of the trash, was a scandal for these people. [Laughs.] But I felt a great interest in the work by Rauschenberg because I see from the nature of this details, a relationship to something which happened in his past. It's an inducement to memory, the work of Rauschenberg. Are all the ties made with the connection to something real, which is fading away, because it's a fact which happened in the distant past when perhaps the artist was young. The quality of this material, which became old because are perishable materials. The paper, the wood, the objects add this kind of distance to the memory, making the object stronger because is alive in the memory. Because it's a matter of fact, but something which we have strong experience in the distant past, is by the memory in some way changed, became more beautiful, because lose reality and get more ideal reality. This process is very strong in the work of Rauschenberg, especially in the ones made in the fifties.Just working my way through. Panza's English doesn't skim very well, but his descriptions of James Turrell installations are fantastic, some of the clearest I've ever read. For example, this account of a 1973 visit to a room in the artist's house, which I confess, I've never heard of--is it a reference to the Main and Hill Studio installations in 1968-70 mentioned in Turrell's bio?:
DR. PANZA: In Santa Monica, in his house, there was another room which was completely dark. This room was nearby a street corner, with lights in the middle of the street. One side of the room was overlooking a small road with a little track. The other side was looking at the main street with many cars passing through. And there was a lamps of public light nearby; there was some small houses nearby. And Turrell, at the end wall of this room, made holes which was possible to open and to close in different positions of the wall. Opening the hole was facing the streetlight, it was possible to have inside the room only the light coming from the red, the green and the yellow light, leaving [off] the light of the street.This use of only found light, it's like those seemingly pop/superficial pieces that use reflected light from TVs showing cartoons, like in the Mondrian Hotel's elevator lobbies, crossed with a quintessentially Los Angeles mockup of the timeless/profundity of Roden Crater. Someone please tell me this still exists.MR. KNIGHT: Of the streetlight?
DR. PANZA: Yes, the streetlight. And the room was filled of, for some minutes, of a beautiful red light. And after, the yellow one. And after, the green one.
MR. KNIGHT: And it would change.
DR. PANZA: And closing this wall but opening another one, it was possible to see only the light projections of the cars which was passing fast in the main street. And this light was coming inside the room like a lightning, filling the room with very strong light, but for a very short time. And afterward disappear; the room became again dark. Opening another hole, it was possible to see only the car coming from the small street, and for some minutes the room was completely dark, but after, some small dim light was coming into the room stronger and stronger. This light had shape, and this shape was going around the room when the car was turning in the main street. And there was a completely different feeling of the light. And opening another one, it was possible to have only the light coming from the far away public light from the street, not the one nearby the house, but one very far. And this light was very dim, but was filling, in a very peaceful way, the room. It looks like the moonlight. It was giving the same kind of emotion, because was visible only the shadow of the objects inside. There was a confused notion of the volume of the space. The room was looking very much larger, almost endless, because there was almost no shadow, a very faint shadow. Everything inside the room was looking like having lost material quality, gaining some kind of ideal entity, which was no more earthly, but heavenly. Something very strange, very metaphysical. And there was a series of this experiences which was very beautiful, made in a very simple way, showing the quality of many kind of light.
update: haha, of course not. It turns out it's the building that used to be called the Mendota Hotel, and the works are his seminal, site-specific, Happening-like Mendota Stoppages. I'd always read Mendota as a studio, not a house [though it was, in fact, both.] Of course it is now a Starbucks.
