Dave Mustaine has confirmed the rock news in a statement, revealing Adler will sit behind the drums for the band's 15th album.
The frontman says, "Chris is a tremendous talent and an amazing person. He's going to bring a new level of excitement and energy to MEGADETH that the fans are going to lose their minds over. I have nothing but respect for my previous drummers, but this is going to kill."
Fans are still waiting to hear who will step in for guitarist Chris Broderick, who quit the band shortly after Drover announced he would be leaving the group in November (14).
