The Mills Brothers

The Mills Brothers were an American vocal quartet active from 1928 to 1982, known for close harmony that blended jazz, pop, and elements of barbershop. Comprised of siblings who often used vocal imitation of instruments to create a distinctive, instrument-like sound, they sustained a long career on radio, records, and in live performance. Their smooth, tightly arranged singing and inventive vocal effects made them a notable presence in early 20th century popular music and influenced later harmony vocal groups.
