To celebrate the release of their fourth studio album, “South Congress,” the World Famous Grassholes will be playing an album release party on the lawn at the Poland Spring Resort, with a matinee show Oct. 4, from 2-4 p.m. The event is free, with a $10 suggested donation to the Poland Spring Preservation Society.

The 11-song “South Congress,” released Sept. 18, is already being hailed as an important work in Maine’s storied bluegrass tradition, with singles “Maybe” and “I Do” getting radio with WCLZ, the Greetings from Area Code 207 Radio Hour, and Portsmouth’s WSCA, plus spins from internet radio station BreakThru Radio. A mix of original compositions and selected arrangements of tracks ranging from Hank Williams to Bob Dylan, the album features lead vocals from all five members of the band as well as hot-picking instrumentals.

A limited run of 300 hard copies have been produced of the album and signed copies will be available at the show. Alternately, the album is in wide digital release, available on all your favorite streaming and digital download services. The hard copies are also available through the band’s Bandcamp site.

As the show will be in accordance with all Maine CDC guidance, attendees are encouraged to wear masks if social distancing is not possible and to keep six feet between parties as much as possible. The event is outside, so feel free to bring blankets and snacks and beverages. Attendance is limited to the first 90 people to arrive.
