Il_Ratrattista,
First of all, thank you

! I'm really glad that you enjoy my work. I'm rather surprised that Another Side isn't on the site as it is completed. I've updated the first post with a .zip file containing all the music that I've completed so far on this project. In regards to Regnum Cor Denique, this is a special track created specifically for this project. It is an ending medley (mainly my attempt at using different KH themes and making my own ending theme to the collection). This is an exclusive arrangement and won't be found anywhere else. And I plan to finish this piano collection in the immediate future (end of this year or early next year). I'm still working on the music when I find time, so you will hear more work from me soon.
On other news,
I will be performing my own arrangement of Passion and Hikari at my upcoming concert. When I get a date for the performance, I hope some of my fans and listeners attend. Not only will there be Kingdom Hearts music played, but also music from other games such as Mario, Final Fantasy VI, Final Fantasy X, Final Fantasy X-2, Final Fantasy XII, Chrono Cross, Chrono Trigger, and SaGa Frontier II. Music from films and anime such as Casino Royale, Memoirs of a Geisha, Cowboy Bebop, Wolf's Rain, Princess Mononoke, Spirited Away, and Howl's Moving Castle. In addition... there will be music from Evanescence and Angela Aki performed. To get more information you can go to my facebook group:

BIG NEWS!!!
I have found a video of someone performing my Hikari arrangement! It is almost perfect with a couple minor mistakes, but for the most part, it rocks! I am impressed with this person's ability to play the piano. See for yourself!
