Review Summary: Guiding lights, I don't know where you've been

15 years. That's how long it's been without a new Pendulum album. For those unaware, after the release of Immersion, the two primary members of the group, Rob Swire and Gareth McGrillen, formed a new EDM project you may or may not know named Knife Party. About two years into that project's existence, Swire admitted that his heart just wasn't in Pendulum anymore, and that he was more interested in chasing that sweet, sweet dubstep/house money because he was enjoying the production and musical aspects of it more. But it seems that the universe took some glee in trolling Rob, because in 2016, he admitted that he didn't like the state of modern EDM, especially the dubstep that he, ironically, had a hand in shaping, and found his heart for Pendulum once more. Things moved quite slowly after that, with a rather underwhelming remix album being their first release back, followed by a pair of EPs: 2021's Elemental and 2023's Anima. Eventually, they decided "screw it" and got to work on the long-awaited fourth album, and they've finally deemed Inertia fit to bestow upon us.

The first thing that's clear from looking at the tracklist is that the band have disturbingly continued the strange trend of releasing EPs and then packing them into full albums, as the entirety of both Elemental and Anima are included amongst the 16 tracks present, meaning that there's only eight new songs present on Inertia. Strangely enough, however, they've been spread out amongst the tracklist: "Driver" and "Come Alive" are placed next to each other and apart from both "Nothing For Free" and "Louder Than Words"; the songs have also been shuffled around so that they aren't even in the same order as they were on their original EP. Sandwiched between them, however, are two of the best tracks Pendulum have ever produced: "Save the Cat" is the first Pendulum track to feature screamed vocals from Rob Swire ("Self vs. Self" from Immersion had screams, but those were courtesy of In Flames mastermind Anders Friden), and they're delivered in what can only be described as something that got detached from a Norwegian black metal band. Even more surprisingly, it works; they deliver a welcome aggression to the industrial undertones of the track. Interestingly enough, the screaming is a recurring theme throughout much of Inertia; tracks like "Archangel" and Wargasm collaboration "Cannibal" are rooted more in the drum and bass parts of Pendulum's sound, with thumping bass and some incredible electronica instrumentation, but feature screaming throughout: "Archangel" in the last few seconds, and "Cannibal" throughout the background and just before one of the last drops of the track.

Speaking of collaborations, Inertia is chock full of them; in addition to "Cannibal", the band also brings along Bullet For My Valentine, Hybrid Minds, Joey Valence & Brae, and even Awolnation and Scarlxrd of all people. And surprisingly, all of the collaborations don't come across as pointless: every collaborator brings something to their respective songs, even if it's a small thing: "Halo" is the best Matt Tuck has sounded in years and is an unholy mish-mash of metal and DnB, the kind that only Pendulum have really successfully figured out how to pull off, while "Mercy Killing" (another EP holdout, this time from Anima) brings in a nice serving of rap that really fills out a song that probably wouldn't have worked as well as an instrumental or even with just Rob. Despite the fact that exactly half of the songs are EP holdovers, they work surprisingly well in the context of the eight additional songs, if only because Pendulum are known for rather bipolar album experiences; the band goes from industrial rock to their trademark DnB to metalcore stylings and pull it off with a conviction that no other band can really lay claim to. Album closer "Cartagena" wraps things up on a rather depressing note, as is tradition for Pendulum, with Rob ranting that "I built this bridge just to watch it burn / Big surprise, we've been drowning forever", but expressing a willingness to keep moving forward, saying that "hope is right there when the day is done", "Don't stop till you feel the light / Oh my god, I feel alone, but that's how I like it", followed by a fade into static, as if Pendulum are walking into the shadows, and hopefully not for another 15 years.

Given the album's roots in electronic music, it's one of the few albums also rooted in rock that actually gets the mixing part done right: every instrument, from the guitars to bass to synths, are able to stand out, and none of them really take precedence over one another; dare I say that Inertia is one of the best-mixed rock albums in quite a while. While it does indeed fall victim to every bad mastering trope in the book, the album is strong enough musically that you can look past those flaws. Even though it's been a decade and a half since Pendulum have released an album, Inertia makes it feel like they never stopped releasing them to begin with, and are ready to show everyone else how electronic music, hard rock, and heavy metal are really done, not just one at a time, but all at once. Start taking notes, kids.

I don't listen to them but the review got me authentically interested, especially if the mix is as good as you stated.

"So we're gonna all die
you know it doesn't feel right."

I know these aren't the official lyrics.

And yeah, nothing is for free.

Cartagena is very pretty, echoes from a better time in electronic music. Sounds like a cut from a 2012 Pendulum album that never got made.



I think it's also notable that some of the older tracks from the EPs got a remaster to fit within the album context, so it's worth relistening to them instead of just skipping to the new stuff. Mercy Killing's guitar doesn't cut through as loudly, which honestly isn't to its benefit, because the crunchy guitar on that track is awesome, but I know some people wanted more low end on it. Silent Spinner is also quieter yet cleaner. These two tracks always had two variants, one super quiet with more bass, and one properly loud with the right frequencies highlighted. Album seems to aim for the middle of the two extremes.



Anyway, very good record, like always.

Just finished listening to this on my way home from work. Not disappointed at all ~ the whole record sounds way more consistent compared to the last two albums



Plus the more guitar-driven songs are fucking lit

Always been a ‘four of five bangers ditch the rest’ album band for me - will be interesting if this one bucks the trend.

So seems similar to usual...I liked Driver, Cannibal, Halo, Napalm and Cartagena first listen.



Lot of the rest the vocal features and choruses weren't the best.



I'll give it the gym slot for the week, see how it grows...

Cannibal, Napalm, Colorfast, Louder Than Words. They could've let some songs off but still...It flows good. It's got more than enough structure. Also, compare this album to how Immersion had Salt In The Wounds at the start? That's like legendary bloat. In Silico was full of bloat too.

Compared to Immersion and In Silico, this one doesn't have as much filler. I can listen to the whole thing front to back without skipping as many tracks
