I am not sure if you are aware of this already but I just found out that Gonzo releases both of them on streaming sites: youtube,crunchyroll and bosttv.
You can even donate to crunchyroll and download the episodes. This is crazy.
Blassreiter and Tower of Druaga are up to episode 2.
This is a great news for people who watch fansubs like me and the death of anime DVDs in USA lol.
