"Jessica" is a rock instrumental written by Dickey Betts, guitarist of The Allman Brothers Band. Jessica was first released on the band's 1973 album Brothers and Sisters, and has subsequently been used in many musical contexts. In January 2006, a Wall Street Journal article referred to the piece as "a true national heirloom." The piece, along with "Ramblin' Man", is one of the two most famous tracks from the album, an album which marked the beginning of a new era for the Allman Brothers Band following the deaths of Duane Allman and Berry Oakley.
