Frank Gehry’s sketches from jam session with Esperanza Spalding are up for auction

Is Frank Gehry the most with-it architect alive? On top of teaching an online architecture class, the Pritzker winner and model train museum designer now has Facebook Live experience under his belt. Last week, Gehry did a one-hour jam session with four-time Grammy winner Esperanza Spalding (who also just wrapped up a 77-hour album-recording marathon live-streamed in its entirety on Facebook—but that’s another story.)

What kind of creative pow wow was it? “Spontaneous.” “Without edit or revision.” “Side-by-side” (at Gehry’s home). Where Spalding supplied the music, Gehry responded with free-form sketching. And now, the results of the sweet collab—Gehry’s drawings and Spalding’s one-of-a-kind composition—are being auctioned off as a bundle, “never to be heard or seen again by the public.”

Below, a selection of Gehry’s output from that afternoon, some of which look vaguely architectural.

The auction will run until Thursday, September 21, with proceeds going toward Bienestar, an Oregon-based non-profit building affordable housing for low-income residents. The lot has an estimated value of $15,000; the current highest bid is $3,500.
