Malcolm B. Wiseman (born May 23, 1925), better known as Mac Wiseman, is a bluegrass singer, nicknamed The Voice with a Heart. The bearded singer is one of the cult figures of bluegrass.
Born in Crimora, Virginia, he studied at the Shenandoah Conservatory of Music in Dayton, Virginia and started his career as a disc jockey at WSVA-AM in Harrisonburg, Virginia.
His musical career began as up-right bass player in the band of country singer Molly O'Day. When Lester Flatt and Earl Scruggs left Bill Monroe's band, Wiseman became the guitarist for their new band, the Foggy Mountain Boys. Later he played with Bill Monroe's Bluegrass Boys. After a performance at the Louisiana Hayride he became popular as solo artist.
During the folk revival in the 1960s, Wiseman had successful concerts at the Hollywood Bowl and Carnegie Hall.
He joined producers Randall Franks and Alan Autry for the In the Heat of the Night (TV Series) cast CD “Christmas Time’s A Comin’” performing "Christmas Time's A Comin'" with the cast on the CD released on Sonlite and MGM/UA for one of the most popular Christmas releases of 1991 and 1992 with Southern retailers.
In 1993 he was inducted into the International Bluegrass Music Hall of Honor. His substantial girth and light tenor voice gave rise to the quip that "Mac Wiseman sings like Gene Vincent looks, and looks like Ernest Tubb sings."
