Some of us are once and future musicians, so this from BitchPhD tells of a way to help we previously didn't know about:
And finally, an additional source for donations that is especially dear to jazz-loving me: the Preservation Hall Hurricane Relief Fund, which will donate 100% of the money raised to New Orleans musicians. Most working musicians, as you know, live a pretty hand-to-mouth existence. Preservation Hall will even give you a free t-shirt if you can donate $150 or more.
While that may initially seem a little back burner to some, consider that many of the Preservation Hall guys are elderly, and clearly don't get paid a ton, so I suspect some, perhaps many, are at the SuperDome or convention center attempting to merely stay alive. And while the money will likely do no immediate good, if it helps during their rebuilding process, that's fine.
