. . . Beefheart was creating more headaches for Zappa. “Ordinarily, a singer goes in the studio, puts earphones on, listens to the track, tries to sing with it and away you go,” Zappa explained. “[But] Don couldn't tolerate the headphones. He wanted to stand in the studio and sing as loud as he could—singing along with the audio leakage coming through the three panes of glass which comprised the control-room windows. The chances of him staying in sync were nil—but that’s how the vocals were done.” Beefheart couldn’t fathom what Zappa was so upset about. “I was playing—just like the whales,” he told Zig Zag. “I don’t think there is such a thing as synchronization . . . that’s what they do before a commando raid, isn’t it?”
