Another one who died on the job – from wiki:
Morphine’s instrumentation was unusual for a rock band: Mark Sandman’s primary instrument was a two-string bass guitar (with both strings usually tuned to a 5th or octave interval) played with a slide; however, on the group’s records he added touches of guitar, piano, electronic organ, and other self invented guitar instruments such as the tritar, featuring two guitar strings and one bass string. Colley played primarily baritone saxophone, along with soprano or tenor saxes, and the rare bass saxophone, and he sometimes played two saxes at once, a la Roland Kirk; he also played occasional percussion, and Dobro on a B-side.
On July 3, 1999, Sandman collapsed on the stage of the Nel Nome del Rock festival at the Giardini del Principe in Palestrina, Italy (near Rome). He was soon pronounced dead of a heart attack and Morphine immediately disbanded.
