Wherever I go, I try to interest people around me in the music of my favourite band, Triumvirat, but mostly, to no avail.
At work I get funny looks kind of like "TriumvirWHAT?" Actually, they kid me a lot, with my obsession with the band. But in terms of actually listening to them or other prog? Most of them couldn't be bothered.
My sisters don't take an interest; they are pretty mainstream in their music taste.
Luckily, my best friend likes prog, and will listen to it with me. Not all is accessible to him, but he does like Triumvirat and Le Orme, for example.
I have another friend who likes progressive music, but we don't listen to it together; he is too busy watching science fiction movies, series, etc. which is ok in itself, but limiting in terms of prog appreciation.
My late father, who was from the generation that grew up on 1940s jazz, actually could get something out of progressive rock; my mother never heard it.
