I would appreciate it if anyone could provide a good quality version of the upcoming score from the series once it is released. Being composed by Murray Gold, who also worked on the Doctor who soundtracks since 2005, I'm sure it will be sterling work and well worth the effort. ;)

In the meantime, does anyone have any news on a potential release date?

No news yet, and the first two Torchwood scores were actually composed by Ben Foster, not Murray Gold. I'm pretty sure Foster is doing the score for Miracle Day.

I know the first two series were actually by Ben Foster, but as far as I know Gold has composed Miracle Day's score:

The Doctor Who News Page: Murray Gold returns to Torchwood (http://www.doctorwhonews.net/2011/03/dwn310311221016-murry-gold-returns-to.html)

Gold and Foster composed the first album together.

I didn't know that. That's great news. There will most likely be a soundtrack later this year or early next is my guess. Probably around the same time we get a soundtrack for Doctor Who Series Six.

Series 1 & 2 were composed by Murray Gold en Foster together
Series 3 composed by Foster, the end Credits used in the series (not on the soundtrack) are by Gold

Series 4 is composed by Murray Gold
