For anyone who likes statistics (and we know Deadheads do!!) the article “A Grateful Dead Analysis: The Relationship Between Concert and Listening Behavior” will be like numerical manna. Written by Marko A. Rodriquez, Vadas Gintautas and Alberto Pepe, the article appears in First Monday: the Peer Reviewed Journal of the Internet Vol. 14, No. 1 January 5, 2009. It presents an analysis of the Grateful Dead’s concert behavior and exposes a relationship between the concert song patterns from 1972 to 1995 and the last.fm listening statistics of the band’s songs from August 2005 to October 2007. It’s a scientific inquiry with technical evidence that will have enduring appeal for nerdheads.
