I dunno. I have to say that if a band is signed to a major label, and has some charting singles, I think that means they are not obscure. The fact that I know 60% of the bands people are listing here suggests to me that they are not really obscure.
Now, gnostalgick, aside from having a very difficult member name, has an excellent list. I haven’t heard of one single band on it, save Antony & the Johnsons and Husker Du. Bravo.
gnostalgick: What genre of music would you put these bands in? If the genre appeals to me, I will explore these bands. Thank you.
