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 : Blassreiter Official Website in English
The Tower of Druaga : The Tower of Druaga Official Website in English

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.
