It’s easy to make a case that the Doors were one of the greatest bands in the history of rock. They were, after all, one of the first bands to top the charts by exploring the darker side of the flower power generation. It’s an equally simple matter to claim the Doors as the godfathers of pretension in rock. It takes a bit more than leather pants and concho belts to signal a death knoll to love power.

The one thing that can’t be argued is that the Doors’ eponymously titled debut remains, over forty years after its release, one of the most auspicious debuts in the annals of rock. As part of its continuing series, Classic Albums: The Doors explores the making of the album, as seen mostly through the memories of the survivors of those sessions. It’s equal parts retrospective and a fond remembrance, as seen primarily through the reminiscences of Ray Manzarek, Robbie Krieger and John Densmore, as well as recording engineer/ Bruce Botnick.

Love them or hate them, when their debut was released in January 1967, there was no band quite like the Doors. The members were educated—film school refugees (Morrison and Manzarek) and accomplished music theorists (Krieger and Densmore) who, consciously or not, would rewrite the rules of rock. They weren’t really interested in teen angst or Utopian visions of love—the Doors looked at what lay beyond those paths, and explored the more shadowy aspects of a world in the midst of a cultural revolution.

Classic Albums: The Doors touches on that mystique, but doesn’t waste a lot of time dwelling on it. Instead, it focuses mostly on the process of making the album. Much of it is anecdotal, of course, largely paced by the perpetually animated Manzarek, who often comes across with a Vegas veneer with his reminisces about the band’s origins. Botnick balances that vaguely schmaltzy exuberance with an engineer’s love of how the songs broke down technically.

Densmore and Krieger provide the greatest insights into how the band achieved its unique sound. Between the two of them, they managed to meld blues, bossa nova, flamenco guitar, and funk in a single riff. With Manzarek, whose keyboard bass and soul and jazz inclinations cemented the Doors’ sound, they emerged as a band that sounded like no other.
