(313) Psychedelic soul

[Cobert, Gwendal]

So... One or two months ago, The Wire had a very interesting feature
about Psychedelic Soul (highly recommended to anybody here who's into
rare groove, Parliament etc), but I have trouble finding some of the
titles ; esp since I only buy CDs (no comments please !). Do you have
great websites for purchasing funk/soul/r&b online, where I might find
my new Grails ?
Stuff I'm looking for : Rotary Connection, Barbara & Ernie, Rasputin
Stash, Swamp Dogg, Debonaires.
