He is best known as a member of the trio 2nd Chapter of Acts, in which he sang and performed with his sisters Annie Herring and Nellie (Ward) Greisen.

Matthew's older sister, Annie was a self-styled (and self-taught) singer and songwriter who wrote and played her songs around the family piano.

Matthew and sister, Nelly would often join in as Annie played and eventually they developed extremely tight and intricate harmonies.

[1][2] As the trio gradually started singing for local coffee houses and small gatherings, they eventually gained the notice of Pat Boone who arranged a contract to record and release two singles with MGM, "Jesus Is" (1972), recorded on Matthew's 13th birthday, and "I'm So Happy" (1973).

He has worked with other such artists as Leslie Phillips, Donna Summer, LeAnn Rimes, Randy Stonehill, Sandi Patti, Dennis Jernigan, Jordin Sparks and many others.
