For the hours I put in combing the interwebs for interesting maths sometimes the best is delivered right to me. True Aristocrats is one such that right off the bat impresses with its inability to be pegged. Is it Mathy? very much so. Most importantly though are the many other complimentary sounds. Electronic elements, bits of noise and a general sense of experimentation rule roost here. Very much wish I ran into more groups that push themselves like this.
Its also worth saying that those drums are all of the map of awesome town.
Its in everyones best interest to at least give it a look.
