On July 14, 1999, former drummer Gar Samuelson died of liver failure at age 41 in Orange City, Florida. Eleven days later, during Megadeth's performance at Woodstock 1999, Mustaine dedicated "Peace Sells" to Samuelson's memory. That month, Megadeth also recorded a cover version of the Black Sabbath's "Never Say Die" for the second Nativity in Black tribute album. The band began a world tour in support of "Risk" in September, playing with Iron Maiden during the European leg. Three months into the tour, Friedman announced his resignation from Megadeth, citing musical differences. Mustaine later said: "I told after "Risk" that we had to go back to our roots and play metal, and he quit." In January 2000, guitarist Al Pitrelli, formerly of Savatage and the Trans-Siberian Orchestra, became Friedman's replacement.
