That'd be at Union Pool tonight, featuring piano-and-cello duets and other plinky sea chanty-type songs, from friend-of-the-L Hannah Marcus (check the haunting, intricate "A Virgin Graveyard", and listen through all the way to the ragged minimalist singalong) and others. Appropriately, as the event is a benefit for the Swimming Cities of Serenissima, the artist Swoon's see-it-to-believe-it fleet of delicately handmade ships (or sculptures?) that will sail from Slovenia to Venice this spring.
So, in conclusion: poetic, pure folk tunes and improbable ships. Also, trapeze?
