Brit-Prog-Djenters TesseracT are currently streaming their new album in full on YouTube. Well worth a listen. I am a big fan of artists offering a 'try-before-you-buy' streaming system: the music should be enough to persuade punters to part with their cash. In TesseracT's case the album is a grower, so it especially benefits from this kind of exposure. Altered State also works well as one continuous piece, as it is presented here.
