In a recent appearance on ‘The Vinyl Guide’ podcast, Metallica bassist Rob Trujillo talked about the confusion of Black Sabbath’s bassist Geezer Butler had while playing the Metallica version of ‘Sabbra Cadabra.’

The legendary band Metallica celebrated its 30th anniversary with four exclusive shows at Fillmore Theatre in San Francisco. The shows featured guest appearances by various musicians, such as Dave Mustaine, Ozzy Osbourne, Geezer Butler, and many more. During the shows, the band recorded their live EP, ‘The 30th Anniversary Celebration,’ on December 9 and 10, 2011 as a part of the celebrations.

During a recent conversation for The Vinyl Guide podcast, Metallica bassist Rob Trujillo remembered their performance in 2011 and talked about the appearance of Black Sabbath bassist Geezer Butler on the show. Together they played Black Sabbath’s Sabbra Cadabra which had different renditions recorded by Black Sabbath and Metallica.

Apparently, during the show in San Francisco, Geezer started playing Sabbra Cadabra according to the Black Sabbath version which caused a conflict between him and Metallica members. As he mentioned in the statement below, Rob Trujillo had to be ‘that guy’ and warned Geezer that Metallica didn’t play in the same key with him in their version of the song.

Here’s what Rob Trujillo stated in the conversation about the memory of Geezer Butler on the Metallica show:

“I became kind of – like a musical director on that. I was helping Geezer play through their songs, we did a medley with them. And Geezer, I remember he was like, ‘It’s not the right key,’ and I was like, ‘I know, I know, but Metallica plays it in this key.’ ‘But that’s not the right key.’ ‘I know, I know, but Metallica plays it in this key.’

And we do this transition into it, and he was like, ‘Okay.’ And he pulled it off. I remember we’re up there playing, but we had to review it, I had to explain why it’s different than the Sabbath version, just things like that, but we got through it.

In my mind, I was thinking, ‘Well, you know, the Metallica version is the Metallica version, but these guys coming on stage to play this song, they’re gonna be used to their version.’ And there are some key changes, and there are some little things here and there, and they got to know this, and my guys weren’t really thinking like that. It’s kind of like get up and rehearse the song.

He continued:

“I was sort of the guy that would go, ‘Oh yeah, by the way, those two chords are these chords’ because in the Metallica version, we transition into that part like this, so I kind of became that guy.

But in the beginning, I was just like, ‘Hang on…’ It was crazy, it was kind of like, ‘Jump in the water and swim.’ So, the challenge in Metallica was that everything was way more intense as far as like, ‘OK, we’re doing a TV show today and tomorrow we’re flying down to LA to play a show for MTV, but then we got a video shoot after that.’

It was just kind of like everything was happening. I was living in LA, and all of a sudden, I get the gig, and literally overnight I was in San Francisco for the next year, and it took, ‘Hold on, I got to get home to get some clothes or something’ – it was intense.

What I did learn from all of that is that I kind of said to myself at one point, ‘I don’t want to go through that again, I am gonna make sure I’m ahead of the game.'”
