This album gathers some world premiere recordings by a composer who for too long has been considered an expression of solely jazz music- Chick Corea. This is the homage to an artist able to merge different genres in his compositions and to combine the experiences of giants of the classical repertoire such as Bach and Debussy, with those of Bartok and Ligeti. With the phrase "This is... music", he shows that he does not want to categorize his compositions in a specific musical genre.
