I really hope this is the last bad anime I cover, this is really starting to drag.

The kingdom of Sforzando has long had in place a barrier to keep demons away from the country but after 15 years the barriers weaken leaving it's Queen no choice but to call for the lost princess to save the Kingdom.
Flute is confused by her new status as a sudden Princess but reluctantly travels to Sforzando under the protection of Hamel, a sorcerer who can defeat monsters with music along with other would be Music Mages, but there's more to Hamel than meets the eye as he may soon find out.
There are two versions of the story, the manga is played more for comedy while the anime goes for dark fantasy drama with Hamel's personality most affected, in the anime he's an angsty edgelord, in the manga he's the jerk hero. I ended up watching the edgelord version, I think the only reason the anime became darker was to not be directly compared to Slayers, Violinist of Hameln does have more creativity to it's plot and plays a good selection of classic musical scores but it's characters don't lend themselves to more serious writing leaving the cast dull and underdeveloped, also it's lack of budget meant that it spends most of it's time with still frames and scenes so darkened you can't follow the action well. It's a pity because the series does have potential.
There's never been a dub although I can easily see the Slayers cast do this anime.
Final Verdict: There's a lot of good things to work with but it's decision to go darker and lack of budget has made the anime dull to watch.
