It's not an exclusively Alternative station, but a fairly wide ranging mix of classics, b-sides, world, electronic, etc. All fairly low-key but interesting.
They introduced me to so many bands over the years. And it is rare to not hear something I fall in love with any time I turn them on.
There was a time that I listened to RP now and again. I distinctly remember a barber I used to go to who had it on in his salon all the the time. They were definitley a pioneer of streaming radio and played a good mix. Thanks for the suggestion @CmndrShrm@lemmy.world
