This isn't a new interview - it was done in 1999 - but it's one of the best I've come across. Tim Powers talks about his life, his writing career, influences, inspirations, his friendship with Philip K Dick, the genesis of William Ashbless and more. Very interesting stuff and it gave me some new insights on his work (which I'm only just beginning to get into).
