The Undertones, a subset of the University of Notre Dame Glee Club, is performing at the Arboretum on the Christ Cathedral campus on Jan. 8 at 7 p.m. The concert is free, but there will be a freewill offering at intermission.

The Undertones are a 12-member all-male a cappella group founded in 1996. Originally formed out of the University of Notre Dame Glee Club, they continue to draw their members exclusively from the now-107-year-old ensemble, among the nation’s oldest collegiate a cappella ensembles. The Undertones perform innovative, original arrangements of music ranging from classic rock to 90s favorites to contemporary hits. They have produced several albums and tour nationally each year from their home base in northwest Indiana.
