Metallica’s “The Call of Ktulu” at Sphere Has Bass Lovers Listening All Over Again

Ever wondered what “The Call of Ktulu” would feel like with the bass demanding as much attention as the monster above the stage? Newly shared footage from Metallica’s October 1, 2026 opening night at Sphere in Las Vegas offers an irresistible reason to revisit the instrumental. The listening hook is simple: follow the low end. For anyone who has wanted those restless bass parts to emerge from beneath the guitars, this is a performance to put on good headphones and explore.

“Have never heard the bass so clear” captures the excitement perfectly. It is the kind of reaction that sends you back into a familiar song with a different priority. Instead of waiting for the next guitar phrase, listen for the movement underneath it: the notes supporting the harmony, the passages pushing against it, and the moments when the bass becomes a character of its own. That shift in attention can make a decades-old favourite feel newly discovered.

The setting makes that invitation even more compelling. In the supplied concert image, Metallica stand beneath an enormous winged creature, with blue and violet light stretching across the screen and the audience gathered below. It is a striking visual translation of the song’s ominous identity. Yet the most interesting way into this footage is through the instruments. A monster can seize your eyes immediately; a bass line can keep your ears returning long after the image has become familiar.

Robert Trujillo’s role deserves that attention. In an instrumental this expansive, the bass has more to do than reinforce a chord or sit beside the kick drum. It can connect sections, introduce a competing melodic shape, and deepen the sense of unease. Listening specifically for his part reveals another route through the arrangement. Rather than treating the low end as background weight, approach it as one of the voices carrying the story.

That is what makes this newly circulating Sphere recording such an appealing listening opportunity. The strongest recommendation is to stay with the passage as the arrangement gathers force, keeping your attention on the bass beneath the repeating guitar figures. There is no need to race towards the finale. Let the instrumental build, then replay it with the same focus. The excitement lies in finding musical detail inside a performance whose visual scale could easily dominate the conversation.

Why the bass matters in “The Call of Ktulu”

“The Call of Ktulu” belongs to Metallica’s Ride the Lightning era, and the band’s official song credits name James Hetfield, Lars Ulrich, Cliff Burton and Dave Mustaine as its writers. Burton’s place in that history gives bass-focused listening a particular resonance. The instrument is part of the composition’s expressive identity, not simply a supporting layer. Hearing how a present-day performance carries that identity forward is one of the pleasures of returning to the piece.

The song is entirely instrumental, which changes the relationship between the players and the listener. There is no sung verse to explain the mood or chorus to announce the emotional destination. Guitar, bass and drums have to establish those things together. A small change in emphasis can therefore have an unusually large effect. Follow a different instrument for a few minutes and the same arrangement can suggest a different path through its tension and release.

Hetfield’s rhythm guitar and Hammett’s lead work give the piece much of its architecture, but concentrating on the bass helps reveal what happens between those landmarks. Listen for where it reinforces the guitars and where it takes its own direction. Both relationships matter. The passages that move together create weight; the passages that diverge create depth. For a listener fascinated by arrangement, this is a richer question than simply deciding which instrument is loudest.

Lars Ulrich’s drums provide another useful point of reference. Try following the bass against the percussion during one replay, then against the guitars during the next. The exercise does not require technical knowledge or a musician’s vocabulary. It simply gives your ears something specific to follow. You may notice an accent, a transition or a supporting phrase that escaped your attention when the entire band arrived as one immense wall of sound.

A new way to revisit Metallica at Sphere

Within the opening-night set, the instrumental followed “Nothing Else Matters” and preceded “Lux Æterna”. That placement gives it a distinctive role: an extended wordless journey between the familiar ballad and the next burst of speed. Metallica’s official setlist confirms the sequence. It also makes the performance an interesting companion to the night’s “Ride the Lightning” appearance, another connection to the same early chapter of the band’s catalogue.

There are two rewarding ways to approach the Sphere footage. Watch it first for the relationship between the tiny figures onstage and the vast creature overhead, then return with your attention fixed on the low end. Each viewing serves a different curiosity. Readers drawn to the screen production can also explore our earlier look at the performance’s dark visual atmosphere. Here, the invitation is to let the bass lead your attention.

For bass lovers, this feels like an especially exciting moment to rediscover “The Call of Ktulu”. Calling it one of the most satisfying opportunities to follow the song’s low end is an enthusiastic listening impression, and the excitement behind it is easy to understand. An instrumental you already know can still offer something unexpected when your attention shifts. Give the bass a full pass of the song, and see how much of the arrangement opens up around it.

The huge creature makes a memorable thumbnail, but the musical curiosity gives the footage lasting replay value. “The Call of Ktulu” rewards attention because its drama is built across an extended arrangement, with several instruments contributing to the same uneasy journey. Sphere supplies a spectacular frame for that journey. The bass-focused perspective supplies a reason to return to it: a familiar Metallica instrumental, heard with fresh priorities and a renewed appetite for what moves beneath the riffs.

Two more Metallica instrumental performances

For a different view of the same composition, watch Metallica’s official “The Call of Ktulu” performance from S&M, recorded with the San Francisco Symphony under Michael Kamen. The orchestral setting offers a fascinating comparison with Sphere’s enormous visual world. Listen to how the band’s instrumental writing sits within the added textures, then return to the Las Vegas footage and follow the bass again. It is a rewarding way to hear the same piece in two expansive settings.

Metallica’s official “Orion” performance from Turin offers another excellent stop for anyone following the bass through the band’s instrumental catalogue. Filmed on Cliff Burton Day, it places a different composition beside “The Call of Ktulu” while keeping the attention on musical development without a lead vocal. Trujillo’s playing makes it a natural companion for this listening approach. Together, the two official performances give the Sphere footage a broader context and a strong reason to keep listening.
