Preservation Hall, (which I'd written about here), a legendary unamplified jazz club. It was everything I'd heard and more.
I bought the whole run of Preservation Hall CDs, and they've been in heavy rotation here. Of the bunch, my favorite is "Songs of New Orleans," and I always know it's going to be a good day when the random number generator smiles on me and shuffles a track from the double CD into my music player, especially if that track is Go to the Mardi Gras, which played about ten minutes ago and put a smile on my face that's certain to last the day through.
I've just noticed that there's a new(ish) Preservation Hall Jazz Band CD, American Legacies, which, alas, I can't say anything about, because the Amazon MP3 store won't sell it to me (I'm in Germany and my credit card is registered in the UK, so they shut me out).
