Book excerpt: Deadhead Social Science is a collection of papers examining various aspects of the complex subculture surrounding the rock band, the Grateful Dead. Deadheads, as Grateful Dead fans are called, followed the band from venue to venue until the band announced their dissolution in December of 1995 and have continued to follow bands including various surviving members of the Grateful Dead since then. Deadhead Social Science addresses the questions: What is a Deadhead? How does a Deadhead identity evolve? Why would a person choose an identity that would be viewed negatively by a larger society? Why are Deadheads viewed negatively by the larger society? Is the Deadhead community a popular religion? How did a rock band develop a religious following? The book also examines the music, the role of vendors, and the reaction by "host" communities to the Grateful Dead and its following. One key theme in Deadhead Social Science is the interconnections among teaching, research, and personal interests written from a variety of social science disciplinary traditions.
