What I'm listening to today: "Soft", Pulp
I'm breaking my format rules here: This song runs from 1:01:09 to 1:05:30 in the linked video (a cassette tape compilation from 1990). This seems to be the only copy of the song on the Internet. I find no other record of the band ("Pulp") existing.
The song is about four minutes of ambient rumbling. I've spent a lot of my life listening to ambient rumbling and this is some of the best rumbling I've ever heard. It's that good.
