Inspired by loud mouth comics like Andrew Dice Clay and Sam Kinison, comedian Jim Florentine, who starts a four-night stand at the Improv tonight, began doing standup comedy in the early ’90s. Florentine’s career took off after just after he released an album of crank phone calls. That led to an appearance on The Howard Stern Show and he became a regular. Florentine has kept plenty busy. He was the co-host of That Metal Show on VH1 Classic. It ran for 14 seasons before VH-1 pulled the plug. And Florentine has had appearances on Girls, Californication and Inside Amy Schumer. He performs tonight at 7:30 at the Improv, where he has shows scheduled through Sunday. Tickets are $17 to $20. (Niesel)
