Trying to figure out why the names on the left are all of living people and those on the right are not. It seems an awkward comparison which begs all sorts of questions about designating as composers people whose music is very rarely performed outside their own direction. But. if you are being serious about absolute comparisons (the Brotzmann x-tets are just FUN groups) then - is there a Braxton composition that in your opinion matches in absolute compositional terms Pli Selon Pli or a Mitchell composition that equals ...explosante fixe... ? Not 'sound world', which as I think you know is a trivialisation of questions of formal composition and artistic purpose, but in absolute terms. Is there a piece by, say, Henry Threadgill, which you consider to have the same compositional novelty and accomplishment, and the same place in the history of music, as Schoenberg op. 9? Just a question, mind you, but one invited by the comparison to concert music. Which is Hemphill's 9th, so to speak - ?
sorry to further derail this thread but whenever somebody brings up villa lobos the following quote comes to my mind
""Why is it that whenever I hear a piece of music I don't like, it's always by Villa Lobos?"--Igor Stravinsky
