Feb. 18 Step Afrika! Holland Performing Arts Center, 1300 Douglas St. 8 p.m., $19-$35, 345.0606, omahaperformingarts.org or ticketomaha.com Step Afrika! should be a real treat for anyone who loves dance but has never seen a step show. Stepping, which is very popular in African-American fraternities and sororities, gets blended here with traditional African dances. Step Afrika! is the world’s first professional step company and this show should be mandatory for fans of world music as well as dance. Its roots grow out of African dance and military marching while using the body as a dynamic instrument, amplified by the dancers’ hard-soled shoes. Think Lord of the Dance, only an African-American version. Truly a rare treat.
