Nick Menza, former Megadeth drummer and current Ohm drummer, died late Saturday night (May 21, 2016) while performing at The Baked Potato in California.
Ohm was three songs into their set, according to their manager Steve Bauer, when Menza suddenly collapsed. Menza was pronounced dead when he arrived at the hospital, but the actual cause of death has yet to be announced- however I have seen a few speculations that a heart attack is what led to his collapse.
As more information regarding his death comes in, this post will be updated.
UPDATE 5/25: TMZ has reported that speculations were correct, and the autopsy shows that Menza did pass from a massive heart attack.
