I find many of Bartok’s works to be harsh and grating, but I grudgingly respect them as I deeply love his other works, the same for Janacek. I do not respect the minimalist composers. I grudgingly respect Robert Moran, the most musical of them, for his music has quality and he writes for the harp.
I do respect Paul Turok, whose harp concerto left me wanting to hear it again, a very rare occurence with contemporary music. I think more people should play it, definitely.
