The Alchemy Index Vols. I & II is the pairing of two distinctly conceptual six-song EPs by So-Cal Warped Tour fave Thrice, which has thus far released five proper albums since 2000. Disc one, titled and conceptualized as "Fire," showcases the still-maturing, melodic, sometimes very heavy post-hardcore that Thrice is forging a career out of, minus any of the emo inclinations from the band's earlier records (no whining, some screaming). By contrast, disc two, "Water," focuses on Thrice's reenactment of Radiohead circa Kid A, with 27 minutes of internalizing, electro-glitch pop steered around by up-front, friendly vocals.
