Risk is the eighth studio album by American thrash metal band Megadeth, released on August 31, 1999. It would be the first album since 1990's Rust in Peace that featured a line change, with drummer Jimmy DeGrasso making his studio debut on a Megadeth album. It would also be the last album to feature long time lead guitarist Marty Friedman, who would go on to announce his departure from the band just a year later.
