Amherst College’s oldest a cappella group, The Zumbyes, will perform at the Darien Library on Sunday, April 15, at 5 p.m. Refreshments will be served.

The Zumbyes was formed in 1950 by a group of eight ambitious freshmen who were more interested in jazz than in traditional collegiate repertoire. During the group’s first year, the charter members practiced nightly in the basement of Stearns Dormitory. It was then that, in the midst of a search for a distinctive name, Steve Miller, charter member baritone, pulled Zumbyes from a hat. And it stuck!

From the very outset, the Zumbyes have adhered to the philosophy that blend is the single most important element of small group singing. Today, the Zumbyes continue to arrange songs with energy, complexity, and significant jazz influence. In addition, the group’s long history allows it the luxury of drawing on tried-and-true jazz favorites that have been arranged, written out, and kept safe by talented Z-alums over the past few decades.

A Zumbyes concert is more aptly called a show — performances are constructed equally around musical fare and irreverent humor.
