First Presbyterian Church of Yorktown

FPCY Concerts on The Corner presents GoldenOak Saturday, June 6 · 7:30 PM&nbsp;GoldenOak began as a duo rooted in close vocal harmony and folk songwriting that has grown into a full band — bassist Mike Knowles and drummer Jackson Cromwell round out the quartet who's performed at the Newport Folk Festival, Tanglewood's Ozawa Hall, the Troubadour in Los Angeles, and venues across the US and Europe. Their sound sits at the intersection of indie folk and Americana: Lena's clarinet and vocals weave through Zak's guitar and harmonies, grounded by a rhythm section. Press has described their music as carrying "the windswept warmth of Cowboy Junkies" with "the acoustic melodic flexibility of Mandolin Orange and The Milk Carton Kids." American Songwriter called their work reminiscent of a late-1960s protest tune. Atwood Magazine called it "a somber, stunningly vibrant and soothing call to action."Their 2025 album All the Light in Autumn marks a new chapter - the songwriting takes on questions of environmental responsibility and community without ever turning didactic. The album artwork features nine birds, one for each song's distinct story. Beyond touring, GoldenOak runs the Under The Oaks Music Festival, a two-day camping event on the Sandy River in their hometown of Farmington, Maine — now in its fourth year, and a testament to the community the band has built around its music.Watch them perform from The Light And The Loneliness: <a href="https://www.youtube.com/watch?v=xgeHglan8bo&amp;fbclid=IwZXh0bgNhZW0CMTAAYnJpZBExT1AwMWZXOGJEUlEwREtMTHNydGMGYXBwX2lkEDIyMjAzOTE3ODgyMDA4OTIAAR6OXCPoACbUDyTdw0-BlNi9NCiesJyDWZQovbiGBm7BsVKvqNwM7ixLRaxnyw_aem_HkRDZKZAB1mUf2Db5Rl5LQ" target="_blank" rel="nofollow noopener">https://www.youtube.com/watch?v=xgeHglan8bo</a><a href="https://onrealm.org/myFPCY/PublicRegistrations/Event?linkString=ZGZhNjgwNjItNGIzOC00NmIzLTg4YjItYjQ0YTAxMzdhOWY5" rel="nofollow noopener" target="_blank">Tickets: $30 / $10 Students</a> <a href="https://fpcyorktown.org/?fbclid=IwZXh0bgNhZW0CMTAAYnJpZBExT1AwMWZXOGJEUlEwREtMTHNydGMGYXBwX2lkEDIyMjAzOTE3ODgyMDA4OTIAAR4qXuWFcixusPd60bb1SUeuViXiCOefFi9olW3-6xrV_6jJ6AohZp-jrazpSA_aem_ZCibLoGlPI7uRY9PyIyqRA" target="_blank" rel="nofollow noopener">fpcyorktown.org</a> · (914) 245-2186
