Susan Robb’s creepy, beautiful, black macro-follicles—she calls them Toobs—will be doing their thing at Volunteer Park this Friday from noon to 6 pm. I haven’t seen the Toobs yet, but word is they are amazing. (If you’re just joining us, Robb took home a Stranger Genius Award in 2003.)

This installment is the fourth Robb has done of this work. It’s called Warmth, Giant Black Toobs no.4. Lawrimore Project—the gallery that represents Robb—will be providing snacks, but you are encouraged to bring blankets and whatever food you like and make a picnic out of it. How could you not? The video alone—and there’s no way a video can capture what it’s actually like—is transfixing:

If it’s overcast on Friday, Warmth, Giant Black Toobs no.4 will be postponed. Because the work is solar powered. Check Slog Friday morning to see if it’s still on.
