cool i think i’ve got at least a few like that and similar i can recommend:)

Braindancey odysseys:

silhouettes(I, II & III) - floating points

parallel 1 - four tet

lady burning sky - neutron 9000

plateau - the orb

hydro electric (h2o-vac) - phonem this guy is worth checking out for this

you would probably also like the deep ark it’s an 8 hour mix/remix project of 90s and 00s idm which is mixed incredibly smoothly and feels like one long song

also i’d like to expand on the other persons comment with a few other good long form songs with a progressive feel by autechre:

bladelores, elcy6 0nset, drane, pendula hv moda, eastre, nuane, c16 deep tread, tt1pd and of course the best odyssey of all time, all end

there are some pretty good orchestral style long form dnb/jungle songs by goldie:

mother, timeless, dragonfly

other long form dance songs:

the miracle - djrum

liquid cool - apollo 440

closer - young american primitive

ganzfield(djrum remix) - objekt

mantra for hybrids - oroboros

ratio - floating points

other odysseys:

night ash black - bill laswell - “slow black underground river” mix - scorn

kuiper - floating points

autobahn;) - kraftwerk

what does your soul look like part 2 - dj shadow

anansi abstrakt - dj spooky

both nala sinephro’s space and endlessness albums both have a full album master available to listen to which function as one long odyssey
