In an anonymous meeting room, a group of people —always eight—gather to sing. Best known for the Broadway hit NATASHA, PIERRE, & THE GREAT COMET OF 1812, Dave Malloy’s OCTET uses chamber-inspired a cappella music to explore the total impact of life online. Hailed by the New York Times as “the most original and topical musical of the year” for its 2019 Off-Broadway premiere, this inventive and acutely relevant piece reflects the perils of the digital age.
