The year in comedy is starting off hot for audiences in Central Florida, with legends like Jim Gaffigan and Patton Oswalt having already headlined Orlando stages. Add to that list Sarah Silverman, one of the most unique performers of this century, whose “Postmortem” tour hits the Hard Rock Live on Friday. Hailing from the Granite State of New Hampshire, Silverman was a writer and performer on SNL back in 1993, but her stand-up career began in NYC, five years earlier.
