A Split-Second is a Belgian electronic body music band. The duo — Marc Heyndrickx and Peter Bonne (under the artist name Chrismar Chayell)—were active from their debut in 1986 until they split up in 1991, and A Split-Second continued as a Heyndrickx solo project. They went on hiatus after a Swedish tour in 1994, and returned to the live scene in 2004. Since 2009, they have been playing live regularly.
