Guitar-amp designer and technician. In 1986, G.E. Smith, who'd just joined Bob Dylan's band, brought Cesar on board to tend to the two guitarists' gear and tone. That began Cesar's six-year association with Dylan. After G.E. left the band, Cesar stepped into the guitarist's slot, playing some 50 dates with Dylan. Cesar also played with Dylan when he won his Lifetime Achievement Grammy in 1991. He left Dylan in '93 to devote more time to his family and amplifier business. He died April 26, 2002 at the age of 50. A letter from César Díaz (things twice)
