Before Josh Dun joined Twenty One Pilots he was in the band House Of Heroes.
That band is currently on a 10-year anniversary tour for their 2008 record “The End Is Not The End”.
As Twenty One Pilots just finished this leg of their “Bandito” tour and House Of Heroes played at the Rumba in Columbus, Ohio, Josh Dun joined them onstage.
Both his sister Ashley Dun and his brother Jordan Dun were there and put some footage of the performance in their Instagram story.
Some fans also filmed the encore and put it online.
​Check out some of the footage below.
