The Dance Theatre of Harlem was formed by Arthur Mitchell and Karel Shook in 1968, an inspired response to the assassination of Martin Luther King Jr. The company grew by leaps and bounds, and the fledgling company was soon one of the high points on the classical dance landscape. And here they are, 58 years later, still touring. Counting 10 stops across the country, the last one in New York City, the DTH tour brings a repertory that includes its celebrated production of Stravinsky’s Firebird, with sets and costumes by Geoffrey Holder, recently re-created by his son, the artist Leo Holder. George Balanchine’s Donizetti Variations upholds the company’s stylistic connection to the New York City Ballet, and Return, choreographed in 1999 by DTH artistic director Robert Garland, rounds out the program. —Laura Jacobs
