“Plasma” is the second hidden track from the standard vinyl release of The Silver Cord and the first on the second side. It was first discovered in the ASCAP ACE Repertory, which lists every band member as a writer. The track’s name is noted in the matrix number on the album’s dead wax. It starts with a pulsing bass synth that turns into a marching rhythm with a number of strange synth parts put over it. In the band’s 2023 Reddit AMA, Stu said the hidden songs were made when experimenting with the sound for The Silver Cord. It’s the shortest of the bonus instrumentals.

“Plasma” has never been played live.
