If ever there were a manifesto for 1970s rock, one that prefigured both the decadence of the decade's burgeoning heavy metal and prog rock excesses and the rage of punk rock, "This Ain't the Summer of Love," the opening track from Agents of Forture, Blue Oyster Cult's fourth studio album, was it. The irony was that while the cut itself came down firmly on the hard rock side of the fence, most of the rest of the album didn't. The album yielded the band's biggest single with "(Don't Fear) The Reaper," a multi-textured, deeply melodic soft rock song with psychedelic overtones, written by guitarist Donald "Buck Dharma" Roeser. The rest of the album is ambitious in that it all but tosses aside BOC's proto-metal stance and instead recontextualizes their entire stance. It's still dark, mysterious, and creepy, and perhaps even more so, it's still rooted in rock posturing and excess, but gone is the nihilistic biker boogie in favor of a more tempered -- indeed, nearly pop arena rock. Agents of Fortune is a solid record, albeit a startling one for fans of the band's earlier sound. It also sounds like one of restless inspiration, which is, in fact, what it turned out to be given the recordings that came after. It turned out to be BOC's last consistent effort until they released Fires of Unknown Origin in 1981.
