London-based Alessi Laurent-Marke performs her tender and charming folk-pop under the moniker Alessi’s Ark. Her music is innocent and quaint, but also vulnerable and intimate — qualities similar to artists like Laura Marling and Mumford & Sons, two acts that she’s shared the stage with many times. Though she’s only 21, she’s already recorded her debut album with producer Mike Mogis (Bright Eyes, Rilo Kiley), released a handful of EPs on major label Virgin Records, and crafted a sophisticated, impassioned sound that seems well beyond her years.
