'IL MENSILE ROCK DI ARCANA' then 'VIAGGIO NELLA MUSICA', the rock music monthly magazine JAM was founded in October 1994 by a group of journalists led by Ezio Guaitamacchi (formerly active at HI FOLKS! magazine) and Mrs. Marialina Marcucci, then President of Videomusic. In January 2014 JAM became an online only publication.
