Composer Murray Gold comments on Doctor Who Series 4 - The Specials album

“This collection is a bit different to the previous releases on Silva Screen. It’s a double CD, of course, and the tracks are drawn from four stories. Previously a single episode has had, at most, three tracks. This time, we linger somewhat longer, and there’s perhaps more a sense of passage through the stories. In some ways, it’s a more conventional soundtrack, with less zipping about through styles. We could have compressed everything onto a single disc, but Silva Screen offered to put out a double. It seemed the better route.”
