Transformers have become the standard solution for various AI tasks, with the query, key, and value (QKV) attention formulation playing a central role. However, the individual contribution of these three projections and the impact of omitting some remain poorly understood. We systematically evaluate three projection sharing constraints: a) Q-K=V (shared key-value), b) Q=K-V (shared query-key), and c) Q=K=V (single projection). The last two variants produce symmetric attention maps; to address this, we also explore asymmetric attention via 2D positional encodings. Through experiments spanning synthetic tasks, vision (MNIST, CIFAR, TinyImageNet, anomaly), and language modeling (300M and 1.2B parameter models on 10B tokens), we discovered that our transformers perform on par or occasionally better than the QKV transformer. In language modeling, Q-K=V projection sharing achieves 50% KV cache reduction with only 3.1% perplexity degradation. Crucially, projection sharing is complementary to head sharing (GQA/MQA): combining Q-K=V with GQA-4 yields 87.5% cache reduction, while Q-K=V + MQA achieves 96.9%, enabling practical on-device inference. We show that Q-K=V preserves quality because keys and values can occupy similar representational spaces and attention operates in a low-rank regime, whereas Q=K-V breaks attention directionality. Our results systematically characterize projection sharing as an underexplored instance of weight tying in attention, with direct, quantifiable inference memory benefits, particularly valuable for edge deployment.

UK doom metal saviors Godthrymm are a damn good band. If you’ve had a chance to listen to either their full-length debut Reflections or their follow-up in 2023’s mighty Distortions, you already know just how talented and outright heavy their brand of doom and traditional metal can get. Then again, you’d also know that their pedigree (with stints in Vallenfyre, Solstice, and of course My Dying Bride, among others) pretty much guaranteed a rock-solid backdrop to their sound. With all that said, I’ve awaited Projections, their final piece to their Visions, for as long as it was announced. Now that it’s upon us, and I’ve had a chance to spend a good, solid week with it, I’ve got some major concerns.
Before I get into the reasons why, let’s focus on the good. There are no poor performances on the album from anybody. Lead-off single “Truth in My Own” is classic Godthrymm through and through, with Hamish Glencross and newcomer Kris McLaughlin throwing down riff after heavy riff, and Hamish’s voice is once again in fine form, especially when he sings alongside his wife, keyboardist Catherine Glencross. Elsewhere, “Endure My Skin” features a fine performance by former My Dying Bride (and current High Parasite) vocalist, Aaron Stainthorpe, reuniting him with Hamish and fellow MDB alumni, drummer Shaun Taylor-Steels. Those two songs are Godthrymm personified.
Sadly, there are four other songs on here,1 and that’s where the concerns lie. Opener “Trenches Deep,” which features Adie Bailey (English Dogs) and Jay Walsh (Xentrix) providing additional vocals, starts off promising enough, but for whatever reason, transitions into a thrash tune that sounds eerily like MDB’s “The Forever People,” and the way it was shoehorned in is anything but natural. At the other end, closer “Hope is Eternal” starts off with an impressive drum fill by Taylor-Steels, and a somber performance by Catherine, until we get to the chorus, which features Catherine wailing “MEEEEEEeeeEEEEEEEEEEEEeeeeeeeeee…” repeatedly. In fact, Catherine features more vocally on this album than Hamish, which isn’t a bad thing at all. I just wish the songs were better, with the other two songs, “Jewels” and “The Sun Never Fell,” not making an impact with me no matter how many times I listen, and no matter who is singing.
It doesn’t help that there are production issues as well. For some inexplicable reason, about halfway through the thrash portion of “Trenches Deep,” there’s a noticeable volume dip, as well as some major compression. I don’t know if this was intentional, but it’s highly off-putting. That volume dip would later reverse itself as “The Sun Never Fell” jacks the volume back up for no reason at all. On my first listen, I thought I was imagining things when it came to the production side, but on repeated listens, they’re right there, and they’re distracting on an album that’s already having a tough time winning me over on a songwriting level. And that absolutely sucks to say, especially since Godthrymm, up until now, has been delivering nothing but slam dunks on each of their preceding albums.
This is not how I envisioned reviewing Projections. In what should have been a hat trick, I’m left baffled and more than a little disappointed. I’m hoping this is just a hiccup, as Godthrymm stand toe-to-toe with the absolute best in British doom metal, rivaling the best that many of the heroes of that genre. With Reflections, they channeled the very best love letter to the classics of yore. On Distortions, they added their own flavor and punch to that sound, resulting in my favorite album of 2023. Sadly, on Projections, I’m listening to this solely for writing this review, and little else. This is not how I wanted things to transpire.

Giornata Internazionale dei Planetari
La Giornata Internazionale dei Planetari torna oggi, il 7 maggio 2026 e, come ogni anno, ci invita a riscoprire il cielo con occhi nuovi. Per chi vuole rileggere il percorso iniziato lo scorso anno, ecco l’articolo precedente:
https://perfettamentechic.com/2025/05/07/giornata-internazionale-dei-planetari/
✨ Cosa cambia nel 2026
Il 2026 porta con sé un’energia diversa: più tecnologia, più inclusione, più “meraviglia accessibile”. Ecco le novità più interessanti.
🌌 Perché celebrarla
Perché i planetari sono ponti: tra scienza e immaginazione, tra passato e futuro, tra ciò che sappiamo e ciò che ancora non riusciamo a spiegare. Nel 2026, più che mai, diventano luoghi dove rallentare, alzare lo sguardo e ricordare che siamo parte di qualcosa di immensamente più grande.

Every era produces its own gods. Not because humans need the #supernatural, but because humans need something to hold their #projections, regulate their fear, stabilize their meaning-making, and mirror their inner world back to them.

To tell you the truth, I no longer believe in gods, angels, devils, demons, spirits, aliens or any other spiritual entities. They do not exist literally, but are found in us as archetypes, in the collective unconscious. These are all my "shadows" and my "projections", nothing else. And my task is to integrate them in my process of individuation. So, enough was enough of fighting, suppression, division and favoring of a certain "camp".
