Fans only have a few more days to wait until Alison Krauss & Union Station return to record stores for the first time since 2004 with new music. 'Paper Airplane' will be released April 12, but you can get the title track today for free, courtesy of the band.

Alison shares with The Boot the inspiration behind the tune, which was written by Robert Lee ("R.L.") Castleman: "When I called R.L., who's been a center of our recordings for the past 12 to 15 years, he said, 'I've been going to the ocean, going to the places I used to go when I was heartbroken and I just can't find it.' After a long conversation, he said, 'Just come over and sit here and talk to me.' So, I drove over there. When I walked in the door, he had a melody and it was 'Paper Airplane.' It was beautiful. I said, 'Well, what are you gonna do now?' He said, 'I'll wait.' I said, 'Wait for what?' [laughs] He said, 'It'll be here about midnight.' It's like a download for him. Completely inspired. He doesn't mess around with it, he just waits. And there it was, 'Paper Airplane.' I just loved it."
