At one point in the bright, mantric hour-long performance ritual which christened Lita Albuquerque’s current sculptural installation hEARTH at the Sunnylands Center & Gardens in Rancho Mirage, a throaty clarion chant rang out across the great lawn, staccato: Got to, got to, got to, got to listen to the silence. Why did you come here? Why do you listen? What does it say to you? In many ways, these are the foundational questions and the essential directive of the entire Desert X affair.
