i will ask my local friend, Joel-Francois Durand, professor of music composition and acting director the School of Music at the University of Washington, classical (20th Century period😁) composer, and builder of my tonearms, whether he disagrees with the Oxford dictionary definition of Classical music.
Och, you don't have to do that. It'd be a bit like asking Robert Plant if Led Zeppelin was a heavy metal band.
There was a thread here a year or so ago and LZ featured as the best HM band of all time. I took issue. Oh, and Liszt is Classic.
