This is the third collaborative album with en avant Music! As the name suggests, this album includes not only classic orchestral pieces, but also a wide range of genres, including fanfares, marches, jazz, and big band pieces. The album's theme,"orchestra," offers a wide variety of expressions, from the dignified and majestic sound of en avant Music to the pop and lively sound of intense Lab. This gorgeous and wonderful album will keep you hooked until the very last track!
