I was to play the drums in order to help the band carry on. “As was said from day one, my place was not to fill all the roles that Mike held in the band. “I understand Dream Theater’s decision to get Mike Portnoy back at this time,” Mangini said in a statement. The band replaced Portnoy with Mike Mangini, who previously worked with Extreme and Steve Vai, among others.
Portnoy left Dream Theater in 2010, shortly after contributing to Avenged Sevenfold’s Nightmare album following the death of their drummer, Jimmy “The Rev” Sullivan. When Did Mike Portnoy Leave Dream Theater? The progressive metal veterans released 10 consecutive albums featuring Portnoy, from 1989’s When Dream and Day Unite through 2009’s Black Clouds & Silver Linings, and became leaders of the genre. Portnoy co-founded Dream Theater in 1985 alongside guitarist John Petrucci and bassist John Myung.
