Like "Waiting for the Man," "White Light/White Heat" is now regarded among the all-time classic rock songs, not to mention one of the most frequently covered. David Bowie cut perhaps the definitive version for a 1972 BBC session (Gary Numan can be blamed for one of the most lamentable), while Lou Reed himself has constantly returned to it, with his most notable reinvention the blinding semi-metal rendition featured on his 1974 Rock and Roll Animal live album. Usually regarded as another of Reed's drug experience numbers, "White Light/White Heat" is, perhaps, the quintessential Velvet Underground song, representing everything that the band itself is said to personify. Recorded at the end of a wearying bout of roadwork, it is the sound of a group kicking out all their frustrations, turning the amps up full and watching them bleed. The song could be about anything -- it is the energy that captivates. Nevertheless, it proved a sad choice for a single, as Sterling Morrison later admitted: "[It] was banned every place. And when it was banned in San Francisco, we said 'the hell with it.'"
