In 2012, Hampton joined forces with Tiana Alexandra-Silliphant to form Hampton Silliphant Management & Productions, which presented the play "Appomattox" at the Guthrie Theater in Minneapolis, Minnesota. The play concerns itself with historic events in America, 100 years apart in time: the historic meetings between Generals Ulysses S. Grant and Robert E. Lee, as well as Abraham Lincoln and Fredrick Douglass in 1865, and the later machinations of Lyndon Johnson, J. Edgar Hoover and Martin Luther King – which ultimately led to the passing of the Voting Rights Act of 1965. "Appomattoxx" was also performed as an opera with Philip Glass at The Kennedy Center in 2015.
