I don't generally make music recommendations on this site, unless I'm asking you to support it by buying a Positron release (which, you'll note, I rarely do.) The reasoning here is that music is a subjective thing, and something that I like will doubtless not be interesting at all to the majority of you. (Obvious ringers being things that you should listen to despite any matters of taste, like Otis Redding, Yo-Yo Ma, Nina Simone, that sort of thing...)
However, I'm gonna break that rule this once. Someone on my CR.net site mentioned in the newsgroup this YouTube video of British soul/jazz/something singer Alice Russell covering White Stripes' 7 Nation Army. I was like "WTF?" when I saw it, and hit up iTunes for her album called "My Favorite Letters." Apparently, it's her second, but I can't find a first.
In any event, it's a hell of a record, with some really crafty production by tm Juke. Leans to modern indie R&B, with some jazz/hip hop/something elements. The label website is so useless I won't even bother linking to it (why is it that indie labels usually have such shit sites?) but you can grab/preview the album through your favorite download service.
