DeRosa of the London freelance scene." Albums As a jazz player, he is recognized as one of the first French horn players to forge a career as a jazz sideman. During his career, he played on important jazz instrumental recordings, including Art Pepper's Art Pepper + Eleven – Modern Jazz Classics, Stan Kenton's Kenton / Wagner, and Johnny Mandel's I Want to Live!. He also appeared on landmark recordings by jazz vocalists, including Mel Tormé and the Marty Paich Dek-Tette, Ella Fitzgerald Sings the Rodgers & Hart Song Book and Ella Fitzgerald Sings the George and Ira Gershwin Song Book, Sammy Davis Jr.'s The Wham of Sam, and June Christy's Something Cool. DeRosa also contributed to important jazz fusion recordings, including David Axelrod's Song of Innocence and groundbreaking albums by Jean-Luc Ponty including King Kong: Jean-Luc Ponty Plays the Music of Frank Zappa. As a sideman on pop records, his contributions to Sinatra's most important recordings are perhaps best known (see with "Work with Sinatra" below). However, he also contributed to many other hit pop recordings such as Barry Manilow's triple-platinum album Even Now, Neil Diamond's hit September Morn, and Louis Armstrong's I’ve Got the World on a String and Louis Under the Stars, two of the most important pop albums from Armstrong's later catalog. As a sideman on rock, blues, and funk records, DeRosa contributed to seminal recordings such as Frank Zappa's first solo album Lumpy Gravy, Boz Scaggs' quintuple-platinum Silk Degrees, and Tower of Power's Back to Oakland, and to rock cult classics such as Harry Nilsson's Son of Schmilsson and Van Dyke Parks's Song Cycle. DeRosa was also an accomplished classical player. He was the hornist on the album The Intimate Bach which received a Grammy Nomination for Best Classical Performance – Chamber Music (1962). Music critic Alfred Frankenstein wrote of DeRosa's performance on this record, "This is the most astonishing example of virtuosity on the horn I have ever heard on records...To play as lightly and speedily as a harpsichord, right out in the open with a minimum of support, is to give an incredible performance." Soundtracks In addition to his work as a sideman, DeRosa appeared on many prominent soundtracks for film, musicals, and TV, including Carousel, Close Encounters of the Third Kind, Edward Scissorhands, How the West Was Won, Jaws, Mary Poppins, Midway, Oklahoma, My Fair Lady, Rocky, The Days of Wine and Roses,
