"Brain Stew" / "Jaded" are two songs by the American punk rock band Green Day. They are the tenth and eleventh tracks and third single from the group's fourth studio album, Insomniac. The two songs were released as one single, as the songs are transitional - "Brain Stew" segues directly into "Jaded". The main guitar riff of "Brain Stew" bears a striking resemblance to the beginning of Chicago's "25 or 6 to 4". After 9/11, "Brain Stew" was placed on Clear Channel's list of post-9/11 inappropriate titles.
The "Brain Stew" part of the song has been played at almost every single one of Green Day's concerts since its release. There have been several notable performances of this song. For instance, when they played it in front of 130,000 fans at the Milton Keynes National Bowl for their live DVD–CD Bullet in a Bible. Another notable performance was when the group performed it at Goat Island in Sydney, Australia on October 19, 2000, where Armstrong mixed up the verses by accident.
The music video for "Brain Stew/Jaded" consists of two parts: The "Brain Stew" portion of the video is sepia toned and depicts the band lying on a couch being pulled through a landfill by a bulldozer, interspersed with shots of Hula dancers and an old lady with a chalkboard. When the song transitions to "Jaded", the video transitions to normal color and fast shots of the band playing the song. The video was directed by Kevin Kerslake.
