This is so sick.
A video has surfaced online of Twenty One Pilots' Tyler Joseph performing his own song - 'Stressed Out' - at a karaoke bar.
"This song I actually wrote myself," he said, before adding, "Let's get the lyrics up here so I can remember the words..."
The whole thing is awesome (obviously) and you can watch his performance below.
Aaaand check out the actual 'Stressed Out' below.
The song is taken from 2015's 'Blurryface', which recently went triple-platinum in the US.
