Music, my 'Famiglia', ELENA, my onstage gear (Gibson Guitar + Mesa Boogie + Marshall = RAAAANGGG!!!!), my true friends (you know who you are), English/American and German literature, videogames and so forth.
EVERYONE!!...The more people you know, the more knowledge you get.
Well, mainly metal, that's what I use to listen to. But I must say that Queen changed my life when I was a kid, and Metallica, as well. Other bands? Well, from Pink Floyd, Joy Division, New order, Coldplay, and Sinatra to Envy, Crowbar, Misery Loves Company, My Dying Bride, Entombed, Most Precious Blood, etc. There are so many influences and bands that I cannot quote them all right now!
The Godfather Trilogy, above all. Furthermore, 'Close Encounters of the Third Kind', 'Intruders'(Based on Budd Hopkins 'Intruders'). Also, Pacino and DeNiro's stuff, 'Goodfellas', 'Scarface', 'Heat', 'Taxi Driver' and so forth.
I use it just to watch DVD/VRC movies... and, of course, when possible, to catch some interesting videos from cool bands in music channels.
Just an 'atomical' part of them: Mario Puzo's 'The Godgfather'; Sam Shepard's 'True West' and 'Buried Child', Arthur Miller's 'Death of a Salesman', Budd Hopkins 'Intruders', etc, etc...
Heroes? No, thanks. Just worthwhile people.
