NPR's All Songs Considered has a brilliant spin-off, which they call The Tiny Desk Concerts. Works like this: they get an artist in to perform a small, (extremely) intimate concert at the (you guessed it) desk of DJ Bob Boilen. They've had some top acts on the show, but my favourite is Tom Jones. Small desk, BIG voice!
You've got to love the computer with Microsoft Outlook flickering on the screen in the foreground.
I wish I could get something like this going at my desk...
