Don't let the cover and title fool you, Vision Fortune are most definitely not an aging mariachi trio. They don't while the day away flittering on acoustic guitars in the dusty sun-bleached sands of Central America. What they actually do, is make violent avante-garde post-rock about the woeful state of the economy from a vaguely anti-capitalist (apparently a main inspiration was the Parable Of The Ox by John Kay) point of view. It's a safe bet to assume that this is a concept album of the highest degree.

Each track runs concurrently, only distinguished by arbitrary severances and Roman numerals, which helpfully don't run in sequence. The sound appears infinite on this, Mas Fiestas con el Grupo Vision Fortune, their debut LP. It's not a standard 'show everyone your best bits' first outing; it's alienating, jarring and complex. The London threesome have issues they need to get off of their chest, and they're going to take the first opportunity they can to offload. On the whole, Mas Fiestas is a droning pit of bubbling rage, with endless percussion and the slow mutation of guitars and/or warped voices. It's post-progressive rock, with some similarities to acts like Tool in the sprawling paeans of deep philosophical ideas.

'XIV' apparently, according to the press release, "brings to mind the inevitable pitfalls of animal husbandry." Realistically, it sounds a bit like a grumpier Kasabian on their most recent album. It's fairly ambitious to attempt to deconstruct capitalism using only a few instruments, and perhaps the group have bitten off much more than they can chew. It's got a primitive, almost tribal feel, created by sparse clatterings of percussion and jerky rhythms; there are grating guitar slides and echoing scratches - it does sound somewhat animistic, but not once are you faced with the plights of cattle. It's difficult trying to give a 'critique' of each song individually, as it's essentially one giant track - a symphony with movements rather than an album with songs.

The noises that Vision Fortune spew are wildly psychedelic, verging upon the psychotic. It's like a peyote induced trance with tie-dye spirit beasts, blurring and melting and blinking out of sync. Then, suddenly and as if from nowhere, there's a vicious streak of malice that burns white-hot, forcing a chill down your spine. The music is hazy, woozy and all kinds of words that end in 'zy', but never let the fleeting softness obscure the very real sinister threat.

While their intentions are so intense they veer towards the ridiculous, it does still have merits as an album. The music won't be everyone's cup of tea, for sure, but it's impressive. If you let it absorb you fully, you probably can/will reach higher planes of thought and attain new levels of spiritual enlightenment. It will stimulate your mind to multiple-epiphanies. Chances are someone'll solve the question 'What's the meaning of life?' to Mas Fiestas. It's too ambitious for a debut, or possibly even music in general, but credit to the lads, they've got conviction, and they've put everything they've got into their ideas. It sounds great, but the complicated skeleton beneath the sonic flesh would do well to remain hidden.
