I once started to collect articles where Robert Wyatt was used as a reference to describe other artists´ music (mostly new artists), but he was suddenly all over the place, and I gave in. Let´s just be satisfied by the fact that Robert Wyatt is a fixed point in the history of music, that may be used by journalists and other crooks (read: bloggers, twitterers and others) to describe or classify other musicians (just or unjust for Wyatt or the others!).
When Robert Wyatt was mentioned in a piece on the recently deceased painter Cy Twombly (1928 - 2011), I found it too good to just leave it! In an article in Spanish La Vanguardia (7 July 2011) called "Abstracto y literario. Cy Twombly (1928 - 2011). El Penúltimo maestro del expresionismo norteamericano", it is written: "Su obra pictórica oscila entre el balbuceo casi blanco y el incendio cromático, entre el estado carencial y la afirmación apasionada. En esto se parece a la música de Robert Wyatt".
You Spanish speaking people may smile at this wonderfully written (I hope!) description, the rest of us have to stick to Google Translate: "His paintings range from almost white babble and fire color, between the iron deficiency and passionate affirmation. In this it resembles the music of Robert Wyatt". I think I get it!
