The Acappella Company's roots in Southern Gospel are deep. Such songs as “When I Wake Up To Sleep No More” and “I'll Have A New Life” provided a traditional foundation for Acappella. But as Acappella explored musical styles and expanded its repertoire to include more contemporary sounds, the group moved away from a Southern Gospel focus. The Vocal Union was formed in the mid-90s to fill that niche and cover those wonderful, heart-stirring classics.

The Vocal Union was originally comprised of members of the studio staff at The Acappella Company, including producers, engineers and interns. The group's success has witnessed a host of talent joining this ministry to continue the legacy of the Vocal Union sound.

The driving force behind the group is Gary Miller – song writer, recording engineer, producer and an amazing bass singer. During his tenure, Miller has led the Vocal Union to new heights including international appearances, top honors in the Contemporary a cappella Recording Awards and a concert at Carnegie Hall. Miller has also contributed songs to other groups in the ministry, including Acappella, AVB, series albums and a forthcoming Praise & Harmony project.
