A longtime fan and musician, Truman has integrated his love of music into comics and illustration. While working for Eclipse Comics, Truman included a Flexi disc recording inside "Scout" #19 (May 1987) that provided a soundtrack to one of the scenes in the comic. He also released an album through Eclipse Records with his band The Dixie Pistols entitled "Marauder". The album included a short comic book featuring the wedding of Emanuel Santanna that took place between the first series "Scout" and the second series "Scout: War Shaman".
