Most underrated composer of 20th Century?

Just a week ago I heard symphonies by Eichberg and I liked them. I had not heard of this composer born in the 1970s. There is a lot of interesting music coming from a wide variety of sources. I even like some of what Golijov is doing, although it sounds like almost crossover to pop music.

Has anyone here listened to the early 1920s opera "Antikrist" by Langgaard? I find that music very interesting--a bit like listening to Hindemith's operas, with a touch of Schoenberg and Wagner. This is another work I happen to stumble upon and liked it a lot.

Schubert, this article addresses your comment about the prevalence of Finnish composers:

Larryi, a few years ago I took part in a performance of a work by Langaard ("Music Of The Spheres"). It was my first exposure to his music and, like you, I found it very interesting; I like your comparison to Hindemith (and Wagner) who as Photon46 says also deserves a place on the "underrated" list. This article is from that concert's program notes; you may find it interesting:

Thanks Frogman, I went to Finland several times when I lived in Germany, would LOVE to live there forever if that was possible.Am an Englund fan.

Re, Glazunov, WI Pubic Radio is playing his Salon Waltz Piano
piece right this second. They play him fairly often and have a CD quality signal, best programming I've heard either here or in Europe.

I am wondering about the interest level of listeners in this thread in composers that are "way out" at the bleeding edge of modernism. For example, do people really love the music of Luigi Nono, or just find it interesting or hate it? I find him interesting, but, I don't really love the music.

What do you folks think of Giacinto Scelsi? I have been listening to some of his works recently and I am sort of coming around on him. Many years ago I purchased an LP of vocal music that employed microtonal singing. Back then, I thought it sounded aweful (I imagined that this is what Yoko Ono sounds like in labor). But now, I find it much more palatable.

I am curious about where other listeners place the boundary of too-far-out-to-listen-to.

Larryi, Yoko Ono in labor, or even not in labor, would be way out of my boundry. Thanks for the chuckle.
