Great 'audio slideshow'over at the Beeb on album design guru Storm Thorgerson, looking at his work from Pink Floyd's debut to Muse (no opportunity to embed unfortunately)
Favourite quote...
"It costs what it costs, and because we do it for real, of course, it's therefore a bit more expensive that doing it on a computer. But better for it"
You get what you pay for...and there's no substitute (even post Avatar) to doing it for real.
