Heather Rigg is on faculty at Broadway Dance Center, where she leads sassy commercial jazz classes. Her performance career includes the Britney Spears “Oops!…I Did It Again” tour and other major 90s acts like *NSYNC, but Rigg, who assisted Frank Hatchett and Joe Tremaine, has always wanted to teach. Here, she teaches a calypso leap without the often-used roll to the floor.
