Heather and Sam, a folk and indie-pop music duo, will perform at the Oasis of Music beginning at 12:30 p.m. on Wednesday, April 19, at the church at Trinity Commons in Lewiston.

Heather + Sam is a side project of the World Famous Grassholes, a five-piece bluegrass band that has been performing for more than two decades across Maine and New England. In duo format, fiddler Heather Kahill and guitarist Sam Pfeifle explore folk and indie-pop pieces they’ve written across the years that maybe don’t fit the full band arrangement.

The Oasis of Music is a weekly music series of performances of roughly thirty minutes, running from September to May. Admission is free, with donations accepted. The musical genres vary greatly, in largely, but not exclusively, acoustic formats. COVID restrictions of optional mask-wearing and social distancing are observed. Trinity Church is located at 247 Bates St., Lewiston. For more information, call 207-344-3106.
