Question: Who wrote the pastiche featuring music by the leading French harpsichord composer of his time, as well as Handel and Vivaldi?

The Denis family were French harpsichord makers from the mid 16th century to the beginning of the 18th century, by which time the Blanchet family had superseded them as the main harpsichord building dynasty in Paris.  Members of the Denis family headed the instrument makers' guild for several generations, but only four harpsichords by members of the family have survived to modern times, and three spinets.  Several of the Denis instruments are signed in red chalk under the sound board with the makers name, place of construction and date, along with three five-pointed stars.  Instruments by the Denis family where in high regard well after their time, as witnessed by an entry in the "Encyclopédie Methodique" from 1785: "The best makers of ordinary harpsichords have been the Ruckers in Antwerp... and Jean Denis of Paris". <SEP> The Concerti Grossi, Op. 6, or Twelve Grand Concertos, HWV 319–330, are 12 concerti grossi by George Frideric Handel for a concertino trio of two violins and violoncello and a ripieno four-part string orchestra with harpsichord continuo.  First published by subscription in London by John Walsh in 1739, in the second edition of 1741 they became Handel's Opus 6.  Taking the older concerto da chiesa and concerto da camera of Arcangelo Corelli as models, rather than the later three-movement Venetian concerto of Antonio Vivaldi favoured by Johann Sebastian Bach, they were written to be played during performances of Handel's oratorios and odes.  Despite the conventional model, Handel incorporated in the movements the full range of his compositional styles, including trio sonatas, operatic arias, French overtures, Italian sinfonias, airs, fugues, themes and variations and a variety of dances.  The concertos were largely composed of new material: they are amongst the finest examples in the genre of baroque concerto grosso. <SEP>  He replaced Jean-Baptiste Lully as the dominant composer of French opera and is also considered the leading French composer for the harpsichord of his time, alongside François Couperin. Jean-Philippe Rameau (] ; (1683--)25 1683 – (1764--)12 1764 ) was one of the most important French composers and music theorists of the Baroque era. <SEP>  It was created by Julian Crouch and Phelim McDermott and premiered by the Metropolitan Opera on December 31, 2011, starring David Daniels, Joyce DiDonato, Danielle de Niese, Luca Pisaroni, and Lisette Oropesa.  The popular 70-year-old Spanish tenor, Plácido Domingo, played the small but important part of the sea god Neptune.  The following month a performance of the "pasticcio" was broadcast live into movie theaters across the world as part of the Metropolitan Opera Live in HD series.  In late 2012, Virgin Classics released this broadcast version on DVD. The Enchanted Island is a "pasticcio" (pastiche) of music by various baroque composers, including George Frideric Handel, Antonio Vivaldi, and Jean-Philippe Rameau, devised and written by Jeremy Sams after "The Tempest" and "A Midsummer Night's Dream" by William Shakespeare.  The Met revived "The Enchanted Island" two seasons later.  Daniels, de Niese, Pisaroni, and Domingo revived their roles from the premiere.  Susan Graham assumed the role of Sycorax from DiDonato.
