The Grayson is slammed when I arrive Saturday night. It’s just a little after 10:30 p.m., but there are crowds of people hovering over the bar, more huddled in the  booths and gathered on the floor. Almost immediately, I spot someone on the dance floor, a friend who I haven’t seen in a while. We say hi and comment on the music and get back into the groove. It’s Italo Horror Night, L.A. Industrial/Dolce Vita’s Halloween party, and the vibe inside is giallo and jams. The Beyond, the 1981 Lucio Fulci film, is playing on a TV above the bar. David Christian just dropped “One Night in Bangkok,” but it’s not the Murray Head version that I know from countless spins on L.A. radio stations. I make a mental note to ask him about it.
