This premiered last night on Vh1, and I just got done watching it on my DVR.
It plays a few times today on their channel as well.

Very good documentary on Deep Purple.
Learned a few things such I did not know Tommy Bolen from the James Gang was one of the players that took over for Ritchie Blackmore.
The video covers the band from the very beginning up to the new album they have in the works that will release in two days called Now What?!
I checked on Amazon, and it shows the MP3s should be available to get on the 30th.
