Here’s a killer supergroup lineup. Tool’s Justin Chancellor, Adrian Smith from Iron Maiden, and System of a Down’s Shavo Odadjian got together on Sunday night to jam out at an undisclosed location.

The occasion was part of birthday celebrations for Nathalie Smith, wife of Maiden’s guitarist.

The System bassist posted a photo to his Instagram the next morning, calling the session a “pleasure” and describing the other musicians as “a couple of legends”.

Good thing the members got together before their schedules fill. All three bands have shows lined up in the new year.

Who would you put in your ultimate supergroup lineup?
