Crappy marketing is generally blamed for Moby Grape's commercial failure in 1967. But in reality the world was unprepared for the band's aesthetic. Although its debut exuded the San Francisco sound, the quintet rocked with all the frenzied angst of punk. And dig those arrangements: they're tight, intricate, and overblown in ways that wouldn't be reclaimed by pop until the glam rock of Queen and Sweet blew up in the '70s. Plain and simple: Moby Grape is one of rock's most visionary albums.
