This fall marks the release of the first two volumes of the series--Fire & Water--while Earth & Air are scheduled for a spring debut. For Thrice, it's the realization of a year-long process of writing and recording, which was done primarily in the band's own studio and engineered by guitarist Teppei Teranishi, without the assistance of an outside producer.

Thrice fans will likely find the thundering strains of Fire to be the most familiar of the four EPs, with the kind of blistering riffs and captivating melodies the band has built a career upon. From the opening bombast of "Firebreather" to the towering, unforgettable "Burn the Fleet," with its Elliot Smith meets Isis vibe, Fire exhibits a Thrice who still know how to punish with decibels, and with greater force and impact than ever before.

Water, on the other hand, offers some of the most subdued textures the band have explored to date, and makes extensive use of a palette of electronic sounds, particularly for rhythms and synthesized effects. Haunting and beautiful, Water is an aural aquatic voyage as serene as it is somber, with the shimmering bliss of "Open Water" naturally coexisting with the dark, moody "The Whaler" and the groundbreaking and evocative instrumental track, "Night Diving."
