TAMUSIC stands for "Try Arrange Music", and it's a group as well as an independent artist. Personally, I just refer to the artist as "Tam". For those that doesn't know about TAMUSIC, and shame on you if you didn't, he's a doujin artist that has previously worked on some Touhou Project arrangements. More information about TAMUSIC can be found on VGMDB and last.fm:
I'm a huge fan of Tam, as well as his works. I'm highly interested in his upcoming album "Puella Magica", more information about that can be found on Tam's official website, which is here! You can also purchase it from this website as well. Full album name is:
TAM3-0076 Puella Musica 魔法少女まどか☆マギカ同人CD
I hope fans of Puella Magi Madoka Magica will purchase this album, so that it encourages him to produce more stuff in the upcoming future. I'm just surprised that he decided to pick up on Madoka Magica, anyways, that's all for this entry! Enjoy!
PS: Some of the songs from his Puella Musica album below~!
