Lou Reed and Metallica covered and absolutely butchered a classic by Reed's former band Velvet Underground last night on "Later ... With Jools Holland".
They played seminal hit "White Light/White Heat", leaving many viewers stunned at what they witnessed.
The collaborative act - who recently released co-album 'Lulu' - also performed "Iced Honey" from that record.

Reed spoke last week about the hate mail he's recieved from angry Metallica fans.
He said: "They are threatening to shoot me, and that's only because I showed up. They haven't even heard the record yet, and they're recommending various forms of torture and death.".
