How do you write an outline for an album [Concept Album]

watch way too many (western) films that match your concept

pick something creative, like a quote or a word, and just build off of it. like my concept beat tape.
Tits.

"beats are like women and the snare are like the tits."-evidence

i love the quote so much i made a beat tape called tits. and made sure the snares were stacked. lol
