Portnoy's comeback was confirmed by the prog metal legends in a PR release today. He exited the fold in 2010 after experiencing burnout and wanting to concentrate on other projects, and was replaced by Mike Mangini, who played with DREAM THEATER across five studio albums and accompanying world tours. Mangini will depart the band upon Portnoy's return.

 

In a series of statements, DREAM THEATER's current members have paid tribute to Mangini while warmly welcoming Portnoy back, with Portnoy himself expressing his delight at returning.
