Qurv Trysr



Released 07.06.2024 

on Point Source Electronic Arts

Qurv Trysr by MTCH is a 9 track, 49 minute album of experimental electronic music. It is like watching gently falling snow at night in torch light - occasional flurries; seeming lulls and persistent, steady accumulation. 

Each fascinating track is intricately constructed from small fragments of synthesised sound which, due to their largely staccato nature, initially, give the impression of random flakes scattered in time, but this would be to miss something important about it, and about snow. 

In fact, the unaccustomed listener could be distracted by the stylistic nature of the composition. However, they will gradually become more aware of the sustained drones and tones underlying the apparent snowstorm. Gently a sense emerges, a language, over the progress of tracks, as everything starts to work together in all its abstract beauty.

Accompanying the album were some notes that stated, ‘It is the sound of crackling electrons burning winding pathways through broken logic circuits, the dry sizzle of overclocked and overheated chips streaming torrents of corrupted data, fragmented and nearly incomprehensible.‘  But there is no final explosion. In fact as you reach the middle of the album, things have slowed and thinned out considerably. The sound palette is continuous but the pace has dropped, creating just enough space for the listener to feel more how the rhythmic elements in music like this work.

Some of the later tracks take the intensity down another notch or two and the drones up somewhat so that the subtleties that emerge reveal a whole other emotionally detailed level to the work that you realise was there all along.

Despite being a very even-tempered album in some ways, each track is very different. The language is quite consistently enunciated but the point changes. Time invested in getting this is well rewarded. 

Qurv Trysr may not give up its nectar to everyone immediately, but if you dwell in it for a while you might just catch a snowflake on your tongue.

MTCH is the project of Mitch Cramer who is based in the US.
