Nickel Creek has released audio for another track from their upcoming reunion album, A Dotted Line.

The song is 21st of May, written and sung by guitarist Sean Watkins from the standpoint of Harold Camping, a California preacher who had forecast May 21, 2011 as the end of the world, or more accurately, the time of the rapture when some Christians believe they would be taken up bodily to heaven.

Stylistically it follows the Doc Watson/Norman Blake model, with a contemporary twist. Have a listen in the video below.

The album is set to hit on April 1, followed by a Nickel Creek performance on A Prairie Home Companion on the 5th. They will then embark on an extended tour through the end of May, with a few dates during the summer. Most of the shows are already sold out, but seats are still available in some cities.

Check tour information on the Nickel Creek web site, where A Dotted Line preorders and instant downloads are enabled.
