I wouldn't call Animal Collective obscure though, they've been on television viewed by millions of people and had feature articles in magazines subscribed to by millions of other people. I like porky's term "cult"...
You could make cases for Lighting Bolt and Wolf Eyes being fairly well-known, but they're not near as big as Animal Collective...
Also, I've said this before, but I must live in the hippest town on earth. Only 40,000 people live here but a good handful of my friends have all discovered stuff as "obscure" as Harry Partch, Cerberus Shoal, Babyland, etc. separately from each other.
And yeah EVERYONE knows Sonic Youth around here and has heard their music...
So, I guess maybe things don't seem as obscure to me because I always hear friends talking about them. One thing, though, is I do live near Bloomington, Indiana which is a popular college town and almost everyone there is a hipster and art lover. Cerberus Shoal actually did play there, that's probably why we all know that amazing band.. but bands as diverse as Genghis Tron, Mong Hang, Xiu Xiu, and Mahjonggg have played there as well. Great, small town.
