Superheroes is the fourth studio album by Racer X. It was released in Japan under the name "Adventure of Racer X-Men"[3] and distributed by Universal Japan. This album was released on Paul Gilbert's 34th birthday.
The track "Evil Joe" contains samples from a prank call made by a friend of Gilbert's to Joe Aufricht of the black metal band Satanicon. The call in its entirety appears as a bonus track on Mushroomhead's 1999 album M3 under the title "Dark and Evil Joe".
