Dennis James (born 1950) is an American musician and historic preservationist. Beginning in 1969, he presented historically informed live accompaniments for silent films, with piano, theatre organ, chamber ensemble and full symphony orchestras, throughout the United States, Canada, Mexico and overseas. He is now primarily active as a noted multi-instrumentalist, specializing on Franklin glass armonica and the theremin, prominently performing in New York at the Metropolitan Opera, for Hollywood film scorings, and repeat performances at Lincoln Center's Mostly Mozart Festival (debuting in 1991 with Roger Norrington and the London Classical Players) plus performing at the Tanglewood Festival with the Boston Symphony Orchestra performing the intricate glass armonica complete part in the U.S. debut of George Benjamin's opera "Written on Skin".
James has also become active in the preservation and restoration of other historic instruments such as the French Cristal Baschet and Ondes Martenot plus has begun performing early syncopated jazz and mid-century moderne styled period-piano repertoire within a multitude of other specialist musical activities generally considered of marginal cultural impact and predominantly subject to the periodic whims of amateurs and enthusiasts.[1]
