27th Aug 1990, Stevie Ray Vaughan was killed when the helicopter he was flying in, hit a man-made ski slope while trying to navigate through dense fog. Vaughan had played a show at Alpine Valley Music Theatre, East Troy, Wisconsin with Robert Cray & His Memphis Horns, and Eric Clapton. Vaughan was informed by a member of Clapton's crew that three seats were open on a helicopter returning to Chicago with Clapton's crew, it turned out there was only one seat left; Vaughan requested it from his brother, who obliged. Three members of Eric Clapton's entourage were also killed.
