Another reader (Shelley), has already written a better review than I think I am likely to manage of USBM, which offers a lengthy overview of the many good elements of Lake's history of US Black Metal, as well as detailing a few well-made and well-articulated criticisms of what is, in many respects, a superb book. The comparison with Dayal Patterson's more international 'Cult Never Dies' series of works covering the evolution of one of the most outre genres of music is apposite - the tone and format of Lake's USBM is not dissimilar, focussing chronologically on the key movers and shakers in a once-derided movement that now stands comparison with black metal made anywhere else in the world.
Part of the issue with this kind of genre exploration is that, frequently, the bands and characters themselves dictate how just how compelling any given section of the book can be. Fundamentally, the personalities that make up the formative bands of USBM (Von, Judas Iscariot, Xasthur, Krieg, Profanatica) are odd, larger than life individuals, who made all pushed the genre forwards in distinctly American ways, while also being (to Lake's good fortune) eminently quotable. As US black metal (perhaps with the exception of the Cascadian revolution of the 2000s) essentially becomes subsumed into the increasingly professionalised and homogenised world of mainstream extreme metal, the chapters become more formulaic - a litany of grizzled, but conventional metallers, detailing the recording and release of sequences of albums that are a little less central to the development of the genre than those released by their forbears in the late 1990s / early 2000s.
That said, Lake's writing is clear and crisp, and he is admirably upfront about some of the less savoury elements of the scene (Inquisition and Nachtmystium, for example). And as a detailed overview of an increasingly well-regarded scene that contains bands as good as Wolves In The Throne Room and Panopticon, USBM is difficult to criticise - Lake has done his job and more here, leaving few stones unturned in his quest to inform and intrigue the reader, and achieving that goal as far as this one is concerned.
