Guilt, that most British of currencies, has rarely sounded so handsomely produced. "I'll See You Soon" arrives wearing its conscience on its sleeve, and credit where it's due: 23 Fields wears it well. This is a single built entirely from the small, gnawing arithmetic of adult life — the missed call, the rescheduled visit, the phone left to ring out while something less important wins the day. It's a theme songwriters return to with the regularity of a guilty conscience itself, yet rarely with this much restraint.

Pop stars used to drown themselves metaphorically in strings and reverb. Skar de Line has gone one further and had himself photographed face-up in wet sand, arms flung wide like a man who's just lost an argument with gravity, while a drone circles overhead like a buzzard deciding whether he's worth the trouble. It's a cover image that does most of the talking before a single note arrives, and thankfully the record inside it doesn't waste that advance.

Oldham has given us many things, but rarely has it given us a band quite so determined to sound like four decades of post-punk and stadium-rock distilled into a single, sweaty rehearsal room — and rarely has the gamble paid off so handsomely. Mercy Kelly, once a five-piece, have shed two members and emerged leaner, hungrier, and considerably more thrilling for it. *Summer of Silence* is the sound of a band finding exactly the shape it was always meant to be in.

Glasgow has never been short of bands willing to plug in, crank up, and dare the room to ignore them, and Delta Fire's third single arrives with the swagger of a group who know exactly which lineage they're auditioning for. "Love Stops First" doesn't so much knock on the door of 70s hard rock as kick it clean off the hinges, dust off the welcome mat, and invite Deep Purple and ZZ Top round for a pint.

Three lads from Wallington walk into a studio in Canning Town, the same room where Blue once cut their pop confections, and decide to make a record that owes nothing to boybands and everything to a man with a red Stratocaster and a laconic Geordie drawl. That, in essence, is "My Guess Is No," the fifth single from Sunday Smoke and the clearest evidence yet that this trio — brothers Benj and Oliver alongside school friend Marcus — know precisely whose shoulders they're standing on.

There's a particular strain of London songwriter who treats the pun not as a cheap trick but as a structural principle, and Tom Minor is clearly working that vein for all it's worth. "Bureau of Change" — the new single trailing his second album, the gloriously titled *Ten New Toe-Tappers for Shoplifting & Self-Mutilation* — takes its title from the currency exchange shopfront and proceeds to wring every conceivable meaning out of the word "change" until the listener is left slightly dizzy and more than a little impressed.

Confession dressed as pop record, or pop record dressed as confession — either way, DARNELL has built something rare: a breakup song that refuses the comforts of villainy. Most songs of this genre arrive armed, ready to indict an absent other. This one turns the blade inward, and the wound it opens is more interesting for it.

Some comebacks announce themselves with a fanfare. Others creep up on you, quietly insistent, like a half-remembered melody hummed in the shower decades after you last sang it properly. Mister Chorister's "Spark" belongs firmly to the latter camp, and it's all the better for it.

Pop has always needed its visionaries and its charlatans, and the trick, more often than not, is telling them apart before the second chorus. Vela Jones, a name that sounds beamed in from a near-future newsroom, arrives with enough cinematic polish to make scepticism feel almost rude. "Star Light Star Bright" doesn't so much announce itself as descend, all synth haze and slow-building tension, like a transmission catching signal after years of static.

There is a particular kind of ambition that announces itself not through volume but through lineage, and Rootless — the Glasgow-based collective who have made a virtue of being from everywhere and nowhere at once — wear theirs like a second skin. Their new single, "Dam Mast Qalandar," takes on one of the most over-recorded, over-sampled, near-untouchable pieces in the qawwali canon — the song Nusrat Fateh Ali Khan turned into a kind of devotional Big Bang — and dares to ask what happens when you run it through a Roma fiddle and a Glaswegian postcode. The audacity alone deserves a hearing.
