Who replaced Steven Adler as Guns N' Roses' drummer in 1990?

Matt Sorum replaced Steven Adler as Guns N’ Roses’ drummer in 1990. Sorum joined after Adler’s departure and played on the band’s major Use Your Illusion-era recordings and tour.

Before joining Guns N’ Roses, Sorum had played with the Cult. Slash had seen him perform during the Sonic Temple tour, and Sorum was subsequently brought in when the band needed a new drummer. Adler’s struggles with heroin addiction and difficulties performing had made his position increasingly unstable; he was dismissed in 1990.

Sorum’s first Guns N’ Roses work included the recording of “Civil War,” although that track appeared on Use Your Illusion II. He then played on Use Your Illusion I and II, released together on September 17, 1991, and performed throughout the massive Use Your Illusion Tour.

The other names in the choices belong to later chapters. Frank Ferrer and Bryan Mantia played during the Chinese Democracy period, while Josh Freese was hired after Sorum’s later departure. Thus Matt Sorum is the single standard answer for Adler’s 1990 replacement.
