The group has debuted “The Foundations of Decay,” produced by Doug McKean, Gerard Way and guitarist Ray Toro.
The last song the group released was “Fake Your Death,” a track they recorded for their unfinished fifth album but instead released on a greatest hits album in 2014.
My Chemical Romance split up just prior to that album.
The group will kick off a reunion tour next week in the UK, then will tour Europe and North America.
