The Mills Brothers, sometimes billed as The Four Mills Brothers, were an American jazz and pop vocal quartet of the 20th century who made more than 2,000 recordings that combined sold more than 50 million copies, and garnered at least three dozen gold records. The Mills Brothers were inducted into The Vocal Group Hall of Fame in 1998. The group was originally composed of four brothers born in Piqua, Ohio, 25 miles (40 km) north of Dayton: John Jr. (October 19, 1910 - January 23, 1936) bass vocalist and guitarist, Herbert (April 2, 1912 - April 12, 1989) tenor, Harry (August 9, 1913 - June 28, 1982) baritone, and Donald (April 29, 1915 - November 13, 1999) lead tenor. Their parents were John Hutchinson (February 11, 1882 – December 8, 1967) and Eathel Mills. John Sr. owned a barber shop and founded a barbershop quartet, called the '"Four Kings of Harmony"'. John Hutchinson Mills senior was the son of William Hutchinson Mills and Cecilia Simms who lived in Bellefonte, Pennsylvania. As the boys grew older, they began singing in the choir of the Cyrene African Methodist Episcopal Church and in the Park Avenue Baptist Church in Piqua. After their lessons at the Spring Street Grammar School, they would gather in front of their father's barbershop on Public Square or at the corner of Greene and Main to sing and play the kazoo to passersby. They entered an amateur contest at Piqua's Mays Opera House, but while on stage, Harry discovered he had lost his kazoo. He cupped his hands to his mouth and imitated a trumpet. The success of his imitation led to all the brothers taking on instruments to imitate and created their early signature sound. John Jr. accompanied the four-part harmony first with a ukulele and then a guitar. They practiced imitating orchestras they heard on the radio. John, as the bass, would imitate the tuba. Harry, a baritone, imitated the trumpet, Herbert became the second trumpet and Donald the trombone. They entertained on the Midwest theater circuit, at house parties, tent shows, music halls and supper clubs throughout the area and became well known for their close harmonies, mastery of scat singing, and their ability to imitate musical instruments with their voices.
After four tunes from 1935-36, which were not at hand to be included previously, Volume 6 in Nostalgia Art’s chronological Mills Brothers CD series covers 22 numbers recorded in 1939, some in New York and most from London, where they also toured England extensively. Much of the material presented here shows The Mills Brothers in a reminiscent mood, performing new versions of songs they had recorded earlier in the decade, but with increased maturity, polish and finesse. The Mills Brothers, with their distinctive brand of “vocal instrumentation” and perfectly blended voices, are the most famous vocal jazz group of all time. Their more leisurely pace on many of these tunes enables the listener to better appreciate the finesse and subtleties of their beautiful harmonies as well as their fantastic vocal imitations of musical instruments.
