Throughout their more than decennial career as a band, Letters to Nepal have continuously redefined their sound, and they show no signs of settling. On past projects, the New Yorkers by way of Siberia have showed ambient post-rock inclinations, building atmoshperic arrangements to emphasize Evgeniya Kuznetsova’s mellow but vivid voice. Their latest track, "TRICKY," shifts towards a sound that’s more electronic, with trip hop overtones (hence the title?). Kuznetsova’s vocals are pushed more to the forefront than ever before, her poetic lyrics meshing nicely with the tranquil electronic production. "TRICKY" is a promising new-new beginning for Letters to Nepal. See them live at Rockwood Music Hall on 6/30. —Henry Solotaroff-Webber
