Arly 2 opens with a series of well-recorded tracks from an unknown source, largely culled from Unrest but demonstrating Cow's penchant for mixing things up in performance so that, while all the signposts of Frith's "Ruins" are there, the complexion is changed by inserting "Half Asleep" smack dab in the middle. Frith doesn't reproduce the razor's edge tone of his solo on the studio version of "Ruins," but his immense, soundscape-like replacement provides an alternate approach that's perhaps even more powerful, before dissolving into a free improv section where the guitarist's innovative approach to prepared guitar techniques are on full display- concepts that he'd mine and evolve further over the years, in ways that would position him alongside Derek Bailey for sheer audacity and textural unpredictability
