For tUnE-yArDs, “Water Fountain” isn’t just the stickiest song from the 2014 album Nikki Nack. It’s also the name of Merrill Garbus’ group’s new nonprofit fund, which raises money to assist with water shortages around the world. You can learn more about that here. But “Water Fountain” is still a hell of a song, too, and last night tUnE-yArDs brought it to the stage at Conan. The tUnE-yArDs live show it a joyous and virtuosic thing, and it’s a blast to see Garbus and her band recreating all those tricky counter-rhythms in real time. Watch the performance below.

Nikki Nack is out now on 4AD.
