Power trio case/lang/veirs, gave us another tease of their upcoming album this week with the fourth song from the self-titled release, "Delirium".

"At first we thought what can we possibly write about, we don't even know each other, there were no themes," Veirs says. "So k.d. and I were having trouble writing and went on a walk. We saw this firework stand and we started looking at the names of the different fireworks, and one of them was called 'Delirium.' We were like, 'that's a good song title,' and we started building. [Neko] came in and, of course, [she] has a way of making everything great. She can even use one word to totally transform a song. We were writing things like 'the walls are falling in,' you know, trying to find a way of saying this person is in a delirious state. She said 'kaleidoscoping in,' and I was like, that's it! One word and the chorus went from cliché to magical."

case/lang/veirs comes is out June 17th on Anti-, and they'll be at the Queen Elizabeth Theatre for Vancouver International Jazz Fest on June 29th.
