The release, due on iTunes March 4, will contain the band's newest single, "Come All You Weary," an acoustic version of "The Whaler" (the original version of which appeared on the Water EP), a remix of "Digital Sea" by Dillinger Escape Plan's Ben Weinman (also originally on the Water EP) and the music video for "Digital Sea."

A stream of "Come All You Weary" is promised on Thrice's MySpace page February 28th.

The Alchemy Index: Volumes I & II: Fire & Water was released in 2007.
