Trev’s Virtual Cassette Library 163

4 January 2026

///vent.making.diverts


Virtual 90 minute mixtapes for the sonically adventurous. 30 artists, two 45 minute sets. A spoken intro followed by music only show. Drops about three times a week. No schedule, just a passion for independent music.

“Hello, Trevor here, and this is episode one‑six‑three of the Virtual Cassette Library. Today’s theme is Vent Making Diverts—which, as usual, is both the track you’re hearing underneath and a location you can find on a map, if you’re the sort who enjoys chasing coordinates on What3Words.
We’ve got ninety minutes ahead—two sides, fifteen tracks each. Some names you’ll know, some you won’t, and that’s half the fun. On the A side there’s an unreleased track by myself which can only be heard here—so if you’re collecting the oddities and outliers, this one’s for you.
On the B side, we’ve got an exclusive from Mist Signals—Someday Soon—taken from the upcoming Whitelabrecs compilation Sleeplaboratory6.0, which drops on the 17th of January to celebrate the label’s tenth anniversary. A decade of quiet experiments, soft-focus soundscapes, and late-night headphone magic.
Now then, starting back on episode 156, there’s a little cipher game running through the series. Each episode, during the intermission, you’ll hear a number. Scribble it down. After ten episodes, you’ll have the full sequence. Put the pieces together, crack the cipher, and you’ll unlock a code that knocks ninety‑five percent off anything on my Bandcamp page. Which means you can scoop up the whole discography for about two quid. It’s not meant to be difficult—just enough to keep you awake at night wondering if you’ll get it right.
The rest of the show drifts through funk, Idm, ambient drift, modular murmurs, rare views, puddles, mythology, and the occasional monkey. The sort of thing you might stumble across late at night on a shortwave dial, wondering if you imagined it.
So—headphones on, let time dissolve, and let the music claim you.”
