I played in the band in my highschool orchestra when we did a production of this musical back in...I think it was 2012. This version here is just the highest quality full recorded version I could find on YouTube. I think it's a community production, rather than professional. This musical, as well as the Skyrim Dawnguard expansion that came out around the same time, is a big part of what kicked off my love of vampire media. It apparently did not do very well in English, though a reworking of it was much more successful in Austria and east Asia.
Which is a shame, because I really love it. I would love to see it performed live. It's one of the most faithful adaptations of Dracula I've seen: certainly more than any movie. It amps up the romance between Mina and Dracula a fair bit for the sake of the musical drama, but IMO that works really well in the format.
