Thirty years ago tomorrow, September 27, 1986, the metal world lost one of its brightest stars. While on tour in support of their magnum opus Master of Puppets, Metallica were involved in a tragic bus accident that claimed the life of their 24-year-old bass prodigy Cliff Burton.

Burton was asleep in a top bunk near the open escape hatch when the drive of the tour bus lost control on an icy road, causing the bus to flip over. The bassist was ejected through the hatch and crushed by the rolling vehicle. It was a tragic end to a brief but stellar career for a man that many consider to be the greatest metal bassist of all time and the unquestionable heart and soul of one of metal’s most beloved bands.

So, to commemorate this somber anniversary, this week’s Massive Metal Monday is dedicated to the memory and legacy of the immortal Cliff Burton. Here is the master performing his signature song live in 1983. This is “Anesthesia (Pulling Teeth).”
