TesseracT began life as a solo project in a dark, cluttered room inhabited by Acle Kahney. With the initial idea to create music with no boundaries, except that it must move you and make you want to groove, embrace and enhance you; giving you what you think you want and then taking you somewhere totally unexpected.

5.0 out of 5 stars Altered State ?? A MASTER PIECE !! 1 Jun 2013
Format:Audio CD
Being a fan of TesseracT, I will admit I had HUGE expectations with this second LP. I consider the suite " Concealing Fate" as one of the most inspiring piece of progressive rock music since "A change of season".
Well, in a nutschell, ALTERED STATE is a mind blowing MASTERPIECE.
To sum up, I would go like this :
- Music : flawless tunes , very well balanced and on top ADDICTING
- Ashe O' Hara 's voice : wonderfull, powerfull and beautifull
- Progressive Density : this LP could be labelled as Top Notch Progressive music , ie : the songs don't go towards 10 musical directions at the same time
- Production : simply astonishing. Ackle and Amos accomplished a great work here. It's spacial, dense, tight and refreshing. In my opinion, the mixing treatment on Drums is fantastic.

The album is a MUST buy. I woud add also that LIVE, TesseracT is a terrific experience. The overall sound of the Band is unique.

5.0 out of 5 stars Game changer 31 May 2013
Format:Audio CD|Verified Purchase
Maybe I don't get out enough but Altered State strikes me as major turning point in the rock/metal scene. It's grandiose but taut; complex yet melodic; ground-breaking and yet familiar. It is, quite simply, a sensation and should be heard to be believed because it's a real treat. I'll refrain from analogising, and just hope you listen to Altered State without any preconceptions; it's one of the most rewarding listens from one of the freshest bands to emerge in decades.

5.0 out of 5 stars Stunning 7 Jun 2013
By Hood
Format:MP3 Download|Verified Purchase
Tesseract's first album was incredible so they had to pull out all of the stops to produce anything of that quality with their second album. Having lost their original singer I was concerned that his replacement (ignoring the first replacement who was dreadful) wouldn't be able match the quality.

Within one listen of this new album I had nothing to worry about. It's simply stunning on all levels. The new singer is superb and the songs are so well crafted that you'll get something new every time you listen to it. Tesseract have produced a work of genius here.

5.0 out of 5 stars Awesome 6 Jun 2013
By Mr Jack
Format:Audio CD|Verified Purchase
Anyone that is a fan of Tesseract, progressive metal and the so-called 'djent' movement will find this epic and compelling. New vocalist Ashe O'Hara does not disappoint either.

5.0 out of 5 stars Just great 28 May 2014
Format:Audio CD|Verified Purchase
Bought this unheard after reading several reviews on other sites, it's just great. For fans of chuggy guitars but without the growling vocals this is just the thing.

4.0 out of 5 stars Progressive metal without the shouty 15 May 2014
Format:Audio CD|Verified Purchase
Tesseract occupy a unique space in the world of contemporary progressive metal, being much more melodic than most of their djenty peers. While much new prog tends now to sound a heck of a lot like all the other prog metal, Tesseract have carved out their own more approachable sound - with simpler and more accessible compositions, and vocals and instrumental lines that your granny might like. It's not everyone's cup of tea, and if you like your prog metal complicated and growly-screamy than tracks with soulful saxophone solos are probably not going to be for you. But I don't know many people - metal fans or just music lovers - who don't like this album when I've put it on in the background.

5.0 out of 5 stars Tesseract - Altered State 8 April 2014
By Gentlegiantprog TOP 500 REVIEWER
Format:MP3 Download|Verified Purchase
Altered State is the second full-length studio album from the British Progressive Metal Band Tesseract. It was their first album to feature Ashe O’Harra on lead vocals, it was self-produced and was released in 2013.

Since getting this album, I’ve been listening to it constantly. It has such a high replay value, and just gets better with each repeat listen. It is such an immersive, cohesive, powerful record and I wouldn’t mind going so far as to call it a masterpiece.

The album is broken down into four sections: Of Matter, Of Mind, Of Reality and Of Energy, which are themselves broken down into separate tracks. The album as a whole flows like one giant song, each of the four sections flow like one continuous song, and each track works on its own. It really is a well-developed and brilliantly executed structure.

Highlights include the powerful “Resist,” the catchy “Nocturne” and the lengthy and interesting “Singularity.”

Musically, there are beautiful shimmering clean guitar sections and a wash of hypnotic electronics subtly mixing with powerful emotive clean vocals with a real haunting quality, there are brilliant rhythmically interesting and groovy drums mingling perfectly with clever bassline, and there’s the odd section of crushing Djenty heavy guitar at the appropriate moments to top it all off. It’s a lot more subtle, intense and driving than their debut, with an almost post-rock attitude to song building. The way things weave and change fluidly makes it a really enjoyable and entertaining listen. Its a real extension and perfection of everything the band have been working towards so far. They even keep things interesting with some well-placed and non-gimmicky use of saxophones.
