Before this thing gets completely derailed, I'll add one.
Rather than a specific group, I never used to "get" a whole genre...Bluegrass.
I never understood why people would like so many HORRIBLE elements all combined into one form of music. Let's see...fiddle, banjo, mandolin, twanging, yodling, folky country music? YUK! Taken separately, I'm not a big fan of any of these elements, especially country music.
I now GET that this is the "original" country music. The tight harmonies, complex time signatures, virtuosic musicianship and even improvisation. It's ALL good.
Very much like "Jazz" has been comandeered by the Kenny G and David Benoits of the world. Many people have no idea what real jazz is anymore. As with all things, the good stuff never gets the exposure or the airtime. I guess that's why we need forums like this, huh?
Nice thread, Kinsekd.
