With the addition of commercials to classical FM radio stations in the "non-commercial" part of the band, it is rare to hear a long suite played all at once anymore. If I want to hear Holtz's Planets as a suite, I have to spin up the record player. And that involves turning over the record after 25 minutes. So certainly, people in the audience should be used to hearing the Gnome on its own.
AbigailKy, are you in Kentucky? Within reach of Wuol Louisville or Wlky Lawrenceburg? You'll know what I mean.
And as far as learning the whole suite goes, I've been working on Pictures at an Exhibition on and off for 30 years. Now that I am retired I am just getting the hang of the final section. But don't expect to hear me on the radio, it takes me an hour an a half still, which would go right across the hourly required radio ID break. Any real audience would dash for the bathrooms somewhere in the middle, and can anybody go without twittering that long anymore? The Louisville Orchestra raced through it in 45 minutes last month. At least I got to hear it live, not on vinyl. My favorite version is Carl Richter and the Chicago Symphony, 1958.
