Whitacre, Holsinger, Ralph Vaughan Williams, Holst and basically anyone else who has written a suite with a march movement, Alfred Reed, Percy Grainger...and some more names will probably float back when I move out of this circle, but after listening to random songs for a few hours, here is the 10-song playlist of Super Highlights I am finally happy playing on loop (may be deleted later).
Equus - Eric Whitacre
First Suite in E Flat - Gustav Holst
Second Suite in F - Gustav Holst
Molly on the Shore - Percy Grainger.
English Folk Suite - Ralph Vaughan Wiliams
Prairie Dances - David Holsinger
Exultate - Samuel Hazo
Incantation and Dance - John Barnes Chance
Hebrides Suite - Clare Grundman (a rare female entrant!)
Armenian Dances - Alfred Reed
(basically: just gimme all the 3-4 part suites & dances ya got)
The really wonderful thing is that I tend to only remember how a few of these go off the top of my head, but the titles snap with instant familiarity from seeing them so often, and as soon as they start I am just blasted away with Feelings and the vague images I associate with the music in my head, which I can't even really articulate because I'm pretty sure half the time it's just that scene from Fantasia representing sound.
