[Lib] Yes - I raved about this in another place back in April. I believe it's going to be at the Whitechapel Gallery, or some such, very soon, and I concur - go see it! [Tuj] His full name is Mordac the Preventer, and he may or may not be a figment of Simons Mith's imagination...
I have several times performed the Tallis in the round - that is, with the eight choirs surrounding the audience. Only then do you get the full sense of the way the music travels through the performers - sometimes working its way round the circle, sometimes bouncing back from side to side. It is a work of the most astounding technical virtuosity - the forty parts are all truly different and independent, yet the resulting complex is very, very nearly entirely free of parallel fifths (a sort of technical shibboleth in Renaissance music) (we found one once, but I can't now recall where it is!). It is said that the piece was conceived to be performed in an octagonal tower in the (long-vanished) Nonsuch Palace, with a choir in a gallery on each side of the tower. (One quibble with the Tate website's description - Spem is hardly a piece of secular music ...)
Wol Breadmaster] I have no idea what you mean ;o) In my artstudent days I composed a piece of music for four suspended washing machine shells. I wired them up with loudspeakers and played through music composed using recorded church bells heavily distorted by volume so that they resonated as they swung. The piece was divided into four movements which progressed from shell to shell. The idea came from a play on the word cycle.
