More than a half century ago Lou Reed would end the sparsely attended shows by the Velvet Underground by leaning their buzzing guitars against the amps, allowing the pulsing waves of feedback to continue long after the band had left the stage. 

Nine years after Lou left for this mortal coil for good, he would likely be pleased to know his guitars and amps are still churning out that feedback.

In the sculpture garden at the Hirshhorn Museum in D.C. one hot Friday this month, a dozen of his amps, some of them out of cases with “Lou Reed Sister Ray Enterprises Inc.” stickers still on them, were arranged in a circle on the grass, between a couple of contemporary sculptures, 

In front of each amp was one of Reed’s own guitars that he had used over the years until his death in 2013, each one turned on and tilted toward the speaker. Where once the guitars rang with “Vicious,” “Walk on the Wild Side” and “Dirty Boulevard,” were now emitting low hums in various frequencies. 

Presiding over the noise was Reed’s own longtime guitar tech Stewart Hurwood, in a T-shirt emblazoned with the familiar image of onetime boss from the 1972 Transformer album.

Hurwood, his hair an explosion of greying curls, would turn a knob here, shake a guitar there, or gently bang the body of a guitar against the ground to conjure more up noise. 

Presented under the name “Lou Reed’s Drones” it was a project of the rocker’s widow Laurie Anderson, in conjunction with the large survey of her art currently on display inside the Hirshhorn, the Smithsonian’s contemporary art museum. The elfin artist herself was tucked away in another corner of the sculpture garden, under a pine tree’s shad, adding her electronic violin and loops to the undergirding drone.
