The Michael Zager Band was a disco ensemble, active primarily during the late 1970s, led by producer, composer, and arranger Michael Zager. Zager's innovative style combined funk, soul, and disco elements, significantly contributing to the disco era's popularity. The band's most famous hit, "Let's All Chant," released in 1977, became an international phenomenon, reaching the top of the charts in several countries. Although the band dissolved by the early 1980s, its distinctive sound and Zager's production techniques have had a lasting influence on dance music.
