Capturing the fraught moment in popular music history as reflected in and anticipated by Since I Left You (2000), the debut studio album from electronic music group The Avalanches.Since I Left You has a reputation amongst its advocates that exceeds those of nearly all of its closest peers. Yet despite the inordinate amount of attention this album has received, it has never been thoroughly examined in context. While repeatedly celebrated for its artistry, technical skill, and emotional resonance - in particular its sample-based material and then-cutting edge technological feats within the electronic music genre - it has never been definitively placed in the world that produced it. Charles Fairchild studies this album in a way no one else has. Since I Left You is placed in its historical, technological, and cultural contexts and is examined for the social and aesthetic attributes it was said to possess at the time of its release. There is a focus on the clear set of aesthetic aspirations that guided the album's creators and how those creators pasted together the fragments of many sound worlds.
