If you're into this kind of music this is Shangri-la

Sorry it's taken me so long to reply - I've been going through some severe domestic upheavals which have made it impossible for me to maintain my pages as much as I'd like. (see my Journal for details if you're interested). Currently the only internet access I get is in 30-minute bursts in public libraries, which precludes proper page maintainence, but I should be back in business within the month, at which point I'll be adding some more links to the Jukebox.
Certainly, though, I have no problem with obscure acts - as you can see from the list as it stands! Frankly, my problem with The Bloodhound Gang is that I HAVE heard them...

agreed (about the bloodhound gang) - they suck big time.
Could recommend a hideous amount of bands and people but will restrain myself to a few:

Plaid, Aphex Twin, Squarepusher, Fila Brazilia, The Herbaliser, Arsonists, Gravediggaz, Mos Def, Black Star, Baby Mammoth, Dr Octogan, Death in Vegas, Kid Koala, David Holmes, DJ Vadim.
Gone but not forgotten: Nusrat Fateh Ali Khan, Lightnin' Hopkins, MC5's, The Boo Radley's.

sorry i'll make myself stop now! Investigate and enjoy!!

I will, and thanks for some excellent suggestions.

I'm happy to tell you that I have finally had the time and the Internet access to start finding websites for some of those acts you suggested for the Music Website Jukebox. I've added Aphex Twin, Mos Def, Musrat Fateh Ali Khan, Lightnin' Hopkins and MC5 links to the Jukebox page today, and will keep looking for the others you suggested. In the meantime, hope you enjoy the aforementioned five sites. The MC5 one is particularly good.
