I've owned this book since 1995, and skimmed key sections many times, but I didn't finally sit down to read it all the way through until recently. Carducci has a provocative and useful concept of small band rock music, and advancing that aesthetic argument (with which I frequently find myself in disagreement) is the primary purpose of the book. In short, he believes 'rock process' occurs when bands with dedicated rhythm sections play together regularly. (So singers with hired session players, groups that favor drum machines - these are all generally outside the definition.) Unfortunately, he devotes nearly half of the text to axe-grinding with the professional music critic press, and railing against various 'scams' - primarily the 'pop scam,' but also the reliably liberal ('commie') culture of rock & pop music writing from the '60s up through the early '90s. While this book was largely penned around 1990, with a major rewrite undertaken for this 2nd edition in '94, Carducci's class-based ressentiment is the sort of thing that continues to drive a lot of American politics to this day - that of working class people who resent the managerial bourgeoisie and equate any kind of left or center-left politics as unfairly redistributing their honestly-got earnings. But what does this have to do with music? Well, Carducci's class-consciousness drives his greater appreciation of various hard-rock and metal forms than is typical in most rock-crit. (He also doesn't give much of a shit about lyrics.) But he also gets tripped up when he assumes that the ink spilled over critical favs like Springsteen and the Clash is all about politics. (And the VU and Captain Beefheart are definitely 'rock,' no matter what point he thinks he's making here by excluding them from his definition.) The more argumentative sections of the book are a slog, though insightful paragraphs pop up here and there. Particularly confounding is his assumption that the rock press should have been covering 'rock' as he defines it, even when it's clear that most of his don't share his narrow definition of what the term encompasses. (And most professional music critics would not claim to specifically cover 'rock' exclusively, let alone his definition of it.) But Carducci's real-life experience in management of the classic indie rock label SST provides much insight into the American indie rock scene of the '80s, and that pops up here and there. The best part of the book, and the part that makes it worth reading/owning, is The Psychozoic Hymnal, a 150 page final section wherein he maps out the various rock scenes going back to the '50s, describing canonical bands and the interaction of their players, and following up with briefs descriptions of thousands of bands, both known and deeply obscure, and figuring out how they fit into his geographic and aesthetic mapping of the music. The final section makes the rest of the book worth it, but he could have written a much better text by confining the axe-grinding to a brief intro and focusing on his vision of rock aesthetics.
