In no particular order:
Tales of Topographic Oceans by Yes.
I know it's not 1974 anymore so you can't listen to this in Ken's dorm room that had a parachute on the ceiling so it was like getting high in a cloud but this is an absolute hightide of prog-rock, marvelous musicianship, complex arrangements, wild mood swings, plethoras of melodies.
Koln Concert by Keith Jarrett.
You can hear Jarret listening on this record, probing and suspending time, and viscerally discovering gorgeous melodies.
Secrets of the Beehive by David Sylvian.
A beautiful record that is nonetheless strange and experimental. Sylvian put a super-group of oddballs together for this, most notably the adventurous, otherworldly guitarist David Torn. I'm still kicking myself for missing this tour.
Come on feel the Illinoise by Sufjan Stevens.
It's wonderful to have counterpoint so lovingly rendered in pop music again. Revivifyingly sweet while being resourceful and surprising.
Kaya by Bob Marley.
I can't live without his voice.
