Metallica drummer Lars Ulrich and guitarist Kirk Hammett had a new conversation with Louder Sound, and shared an untold stories about Metallica’s legendary bass guitarist Cliff Burton.

Kirk said that Cliff made a great contribution to Metallica’s sound. However, according to Kirk, Cliff had his own style and sometimes it was so interesting to watch what he would do next.

When Cliff was writing Anesthesia (Pulling Teeth), he was in a so different mood. Lets hear what Kirk said:

“I remember him recording his bass solo separately from anyone or anything. He was upstairs in this big empty room, standing there alone, just him and his bass amp.

I watched him play while they were getting his sound right downstairs in the control room.

After 15 or 20 minutes, he got the sound right and then he looked at me and said: ‘Get away from me, man – I’m about to do this.’

And then he took a hit off a joint, bent over and drank a beer, and I hightailed it out of there.”

Also, Lars Ulrich talked about Anesthesia and how Cliff contributes that song:

“Anesthesia was a bass solo disguised as a song, instead of it just being called ‘Bass Solo.’

It was like what Geezer Butler did in Black Sabbath – he just gave it a clever, cool title.”
