I'm not sure of the TB sound track, but I just received vol. 3 on DVD on 05/31/11 via Amazon.com - the was a great deal too, only $29.99 (originally $36 on Amazon). If you were to go to the HBO website and to the TB section, you might locate the release date for the sound track. I suspect it is now available via iTune, since the DVD is now available. Enjoy!
