Bill Graham's Day on the Green concerts were the first prototypes of "festival" shows - multi performer sets in stadium settings. Staged on the lawn of the Oakland Coliseum, the Day on the Green concerts were a summer series started in 1973 that continued until shortly after Graham's death in 1991.
Michael Zagaris, known as 'the Z-man', offers the performer's eye view in his photography. Zagaris became the Stones, the Who, Led Zeppelin; not vicariously but actually. He donned the make-up and ran down the tunnel onto the stage. As an insider in those days, he took photographs of what was, not what one expected to see, and as an insider today he does the same thing for 21st century bands and artists. As team photographer for the San Francisco 49ers, a title he achieved in '73, and for the Oakland A's, Zagaris is sports' inside-out shooter. Ankles taped and knee pad-clad, he's the guy so familiar to the players that they see him as their own.
