That's where the genius kicks in..sustaining it through a 20 minute movement. You should take a swing at it. Have you written any symphonic stuff? :D:D
yes.
i did a project a few years back,
with a band out of british columbia, called "FALSE HARUSPEX"
http://falseharuspex.aeriemonks.com/ It is a one-hour long continuous instrumental,
broken up into 13 unique sections.
it did quite well!
took me about 6 months to complete my parts (the solo guitar throughout)
after i did my parts, the original group then added crunchy rhythm guitar parts, to augment my stuff,
then added synth and voice on top of everything else once the arrangements were complete.
i have many instrumentals that i rarely post,
typically they are in the 5-8 minute range,
instrumentalists typically really get off on them, and no one else does.
