Bell made his Carnegie Hall debut in 1985, at age 17, with the St. Louis Symphony. He has since performed with many of the world's major orchestras and conductors. As well as the standard concerto repertoire, Bell has performed new works. Nicholas Maw's violin concerto is dedicated to Bell, who premiered it in 1993 and won a Grammy Award for his recording of the piece. He performed the solo part on John Corigliano's Oscar-winning soundtrack for the film The Red Violin and was also featured in Ladies in Lavender. Bell made an appearance in the movie Music of the Heart, a story about the power of music, with other notable violinists. 　　Bell's instrument is a 300-year-old Stradivarius violin called the Gibson ex Huberman, which was made in 1713 during what is known as Antonio Stradivari's "Golden Era." This violin had been stolen twice from the previous owner, Bronisław Huberman; the last time the thief confessed to the act on his deathbed. Bell had held and played the violin, and its owner at the time, violinist Norbert Brainin, jokingly told Bell that the violin could be his for four million dollars. On 3 August 2001, Bell was in London to perform at The Proms, and stopped by J & A Beare before the concert. There, he learned that the violin was there, and about to be sold to a German industrialist to become part of a collection. Bell played this violin at that Proms concert that same evening. He later sold his previous violin, the Tom Taylor Stradivarius, for a little more than two million dollars and made the purchase of the Gibson ex Huberman for a little under the four million dollar asking price. The story of the theft, return, and subsequent acquisition by Bell is told in the 2013 documentary The Return of the Violin, directed by Haim Hecht. Bell's first recording made with the Gibson ex Huberman was Romance of the Violin (for Sony Classical Records) in 2003. 　　Bell has served an artistic partner for the Saint Paul Chamber Orchestra from 2004 until 2007, and as a visiting professor at the Royal Academy of Music in London. He also serves on the artists' selection committee for the Kennedy Center Honors and is an Adjunct Associate Professor at the Massachusetts Institute of Technology. 　　Bell was awarded the Avery Fisher Prize on April 10, 2007, at Lincoln Center in New York City. The prize is given once every few years to classical instrumentalists for outstanding achievement. On May 3, 2007, the Indiana University Jacobs School of Music announced that Bell had joined the faculty as a senior lecturer. 　　Bell collaborated with film composer Hans Zimmer by providing violin solos for the soundtrack of the 2009 film Angels & Demons, based on Dan Brown's 2000 novel of the same name. 　　In May 2011, Bell was named the new Music Director of the Academy of St Martin in the Fields (ASMF). Bell has recorded commercially with the ASMF for the Sony Classical label. In July 2017, the ASMF announced the extension of Bell's contract through 2020, an additional three years from his previous contract extension. Bell and the orchestra won the 2017 Helpmann Award for Best Individual Classical Music Performance. 　　In 2013, Bell accompanied Scarlett Johansson in the song "Before My Time". Written by J. Ralph for the documentary Chasing Ice, the song received a nomination for the Academy Award for Best Original Song. 　　In other media, Bell played himself in three episodes of Mozart in the Jungle in 2014, 2015, and 2016: the pilot episode, Touché Maestro, Touché, and Creative Solutions for Creative Lives. In 2016, he played a cameo role on the penultimate musical episode of Royal Pains. He also appeared as himself in episode 8 ("Quacktice Makes Perfect") of the 2017 Netflix original series Julie's Greenroom.
