Here’s a recent tune by Lorelle Meets The Obsolete, the Mexican band I saw on the spur of the moment on Tuesday night. I’d never heard of them but it was a great decision to go, and now I’m discovering their records.

It seems they’ve been becoming increasingly experimental, and noisier, since they were formed a decade ago by Lorena Quintanilla and Alberto Gonzalez, smothering their psychedelic shoegazey sound in waves of industrial noise.

What was once light and pop-influenced has become dark and mysterious with an evil intensity that suggests lurking danger, often with a gloomy, narcotic tempo but sometimes a relentless monotony; never more so than on this increasingly frightening number, Golpe Blanco, with Lorena Quintanilla’s quiet vocals accentuating that eerie vibe.

A throbbing bass guitar and thunderous drums set the tempo for most songs, those hazy guitars – distorted through all sorts of foot pedals – now serving mostly to embellish the dark shards of electronic noise coming from a bunch of analogue synths.

The space in the tunes suggests a dub influence, though it’s far removed from reggae; more of a mood, spreading slowly like an oozing blood stain. Which is an apt metaphor for the unsettling experience of listening to their most recent album, Datura.
