One of the most important dancers and choreographers of the last century, Twyla Tharp has been pushing modern dance forward for more than 50 years. With her latest show, “Minimalism and Me,” currently in the midst of a three-week run at the Joyce Theater, she revisits the creation of her influential early works and their relationship to the minimalist art movement of that era. On Thursday’s “Leonard Lopate at Large,” Twyla Tharp discusses “Minimalism and Me” and the seminal dance performances from 1965 to 1971 that inspired it.
