Unity 4 has sung many styles over the years, but in the last decade, they have focused on preserving a dying breed of gospel music....traditional all-male four-part harmony. They have become known for their rich harmonies and classic song selection. They began not only to sing songs of years past but began writing their own material while holding true to the standards of the past quartets and their arrangements. Examples of songs written by members of the group (and/or their family members) are "Quartet Singin'," "Cast Your Cares," "Meet Him In The Air," "Back To The Well," "He Never Gave Up On Me," "My New Neighborhood," "The Only Book," "The Lord Is Everything," "I Have A Happy Feeling," "No Wonder," and "The Ransom."
