On the cover

Photographer Eric Draper shot this striking image of Richard A. White (see "Big Brass, Bigger Dream") under the bright lights of the stage in University of New Mexico's Keller Hall. "I wanted to show that Richard is a uniquely gifted artist with starlike qualities," he says. "My goal was to illustrate his physical presence, which actually reflects the tone and bravado he creates with his tuba. Richard and his tuba are a perfect match." Draper, based in Rio Rancho, New Mexico, was President George W. Bush's chief photographer for all eight years of his administration.
