In 2004, Wired editor Chris Anderson outlined the Long Tail hypothesis. The prophetic business theory claims that the Internet revolutionizes niche markets, allowing new models for personally tailored products to emerge. Subverting the bestseller race with a series of hyper-targeted relays, the phenomenon has fundamentally shifted the way book publishers now approach music. Many houses have begun to test the waters of super-specialized music books — everything from obscure band bios and lost-music anthologies to memoirs, road diaries, and journalistic diatribes. Meanwhile, imprints such as Continuum — home to the popular 33 1/3 series — and Process have emerged to document music's outer edges.

Sure, the advent of such music books is a boon for out-and-out obsessives, but what about the more casual reader, who, you know, just really likes to rock? Plucking accessible oddities from the maelstrom of esoteric dorkitude can be a bit like exploring Bob Dylan's extended discog (stick to Highway 61's smooth pavement and you're fine, but take one misstep, and you're wallowing in some pretty thick weeds). On the other hand, it's impossible to ignore the allure: hidden in the brush are stories that make Mötley Crüe's Behind the Music look like a month with the Monkees. So, how to unearth engaging music books without ending up unbelievably bored? Like the polka, the waltz, and the pony, it takes a little rhythm and three simple steps.

1. Start small or, rather, well-regimented.
It's not the length, but the density that makes or breaks a niche-music book. Like the snarky, down-and-dirty Devo songs it explores, Simon Reynolds' Rip It Up and Start Again is at once inviting and alienating — an exhaustive, rigidly executed exploration of late-'70s and early-'80s post-punk. While the insider knowledge and obscure facts on bands like the Fall and Devo make this the be-all and end-all for genre buffs, at 432 tightly packed pages, it's a bit overwhelming. By contrast, Michael Azerrad's 522-page-long Our Band Could Be Your Life reads faster than many books half its size. Why? Azerrad segments his exploration of the '80s American indie underground into individual (yet often intersecting) biographies of 13 landmark bands. The result is an evolving narrative that balances the engaging anecdotes of acts like Black Flag, Mudhoney, Sonic Youth, and Fugazi with enough history and trivia to keep the nerds in check.

2. You get more insight (not to mention laughs) from a self-effacing insider.
While there's plenty to be gained in the bios of big boys like Bob Dylan, it can be a lot more interesting to hear from, say, a man who watched as the wild-haired folkie moved in on his woman. White Bicycles , for example, is producer/promoter Joe Boyd's autobiographical account of a life spent traveling with Muddy Waters, booking Pink Floyd, and burning the midnight oil with Nick Drake. Boyd is a grounded figure from the '60s UK folk scene who happened into the lives of some famous folks. Because he's not concerned with his own importance, his insights and anecdotes resonate more deeply — offered, as they are, through the lens of a relative everyman.

3. Avoid anyone saying everything was totally awesome.
If a book requires specialized knowledge, its author is often drawn from a pretty tiny pool. Kim Cooper's In the Aeroplane Over the Sea is ostensibly a book covering indie band Neutral Milk Hotel, but it's actually about the '90s neo-psych scene that birthed it. The author was given unprecedented access to a number of reclusive artists. Unfortunately, this free pass seems to be predicated on personal connections, so her overwhelmingly upbeat statements come across as suspect. Because of the insider's propensity for painting everything pretty, an informed outsider is ultimately your best bet. In Matt Diehl's My So-Called Punk , for example, the author is personally acquainted with the '80s punk movement, but he uses that knowledge to explore the genre's evolution into the '90s. This slight distance allows him a more critical outlook, and the result is a far more evocative analysis of punk's move into the mainstream than anyone involved could offer.
