Input: Question: Which of the movies whose soundtracks Atlan is known for making original arrangements from had the highest box office sales? Passage:In October 2010, Joe Atlan started uploading his music to YouTube. In just a few days, one of his piano songs received more than 100,000 views. Since that moment, Atlan has used YouTube as the main way to share his music, projects, and stay in touch with the fans. His videos are a display of musical experimentation, sometimes with a touch of humor, usually combining instruments and sounds with no particular Genre, or making original arrangements from movie soundtracks, such as The Hobbit, Star Wars, or Pirates of the Caribbean. Atlan tends to show virtuoso skills as an entertainment and way to practice, specially using his Roland AX-7 Keytar, which has become his signature instrument. He also shares his piano compositions there and publishes them for free. Joe Atlan's songs are usually instrumental piano tracks with an epic fantasy, oceanic and hopeful atmosphere. His work on YouTube is often featured in digital magazines and music-video websites. In 2013, Atlan was also contacted by the Dubbing and Voice actor who does the official Spanish voices of Morgan Freeman, Ian McKellen among others, to start a project combining Music and Poetry.
