Copperhead Copperhead {acadia+sony Aca 8005} (1973)

In retrospect, it's a bit shocking how fully formed the signature Aerosmith sound was on their self-titled 1973 debut – which may not be the same thing as best-executed, because this album still sounds like a first album, complete with the typical stumbles and haziness that comes with a debut. Despite all this, Aerosmith clearly showcases all the attributes of the band that would become the defining American hard rock band of the '70s. Here, the Stones influences are readily apparent, from the Jagger-esque phrasing of Steven Tyler to the group's high-octane boogie, but the group displays little of the Stones' deep love of blues here.

Indulging for the first time in Cockney Rebel's debut album – and one uses the word "indulging" deliberately, for like so much else that's this delicious, you cannot help but feel faintly sinful when it's over – is like waking up from a really weird dream, and discovering that reality is weirder still. A handful of Human Menagerie's songs are slight, even forced, and certainly indicative of the group's inexperience…

Mike Oldfield's groundbreaking album Tubular Bells is arguably the finest conglomeration of off-centered instruments concerted together to form a single unique piece. A variety of instruments are combined to create an excitable multitude of rhythms, tones, pitches, and harmonies that all fuse neatly into each other, resulting in an astounding plethora of music. Oldfield plays all the instruments himself, including such oddities as the Farfisa organ, the Lowrey organ, and the flageolet. The familiar eerie opening, made famous by its use in The Exorcist, starts the album off slowly, as each instrument acoustically wriggles its way into the current noise that is heard, until there is a grand unison of eccentric sounds that wildly excites the ears.

With Ringo, Ringo Starr finally put his solo career in gear in 1973, after serving notice with back-to-back Top Ten singles in 1971 and 1972 that he had more to offer than his eccentric first two solo albums. Ringo was a big-budget pop album produced by Richard Perry and featuring Ringo's former Beatles bandmates as songwriters, singers, and instrumentalists. On no single track did all four appear, though George Harrison played the guitars on the John Lennon-penned leadoff track "I'm the Greatest," with Lennon playing piano and singing harmony. But it wasn't only the guests who made Ringo a success: Ringo advanced his own cause by co-writing two of the album's Top Ten singles, the number one "Photograph" and "Oh My My"…

Emerson, Lake & Palmer's most successful and well-realized album (after their first), and their most ambitious as a group, as well as their loudest, Brain Salad Surgery was also the most steeped in electronic sounds of any of their records. The main focus, thanks to the three-part "Karn Evil 9," is sci-fi rock, approached with a volume and vengeance that stretched the art rock audience's tolerance to its outer limit, but also managed to appeal to the metal audience in ways that little of Trilogy did. Indeed, "Karn Evil 9" is the piece and the place where Keith Emerson and his keyboards finally matched in both music and flamboyance the larger-than-life guitar sound of Jimi Hendrix. This also marked the point in the group's history in which they brought in their first outside creative hand, in the guise of ex-King Crimson lyricist Pete Sinfield…
