Music and Arts in Leipzig
Johann Sebastian Bach worked in Leipzig from 1723 to 1750, at the St. Thomas Lutheran church, and Richard Wagner the composer was born in Leipzig in 1813, in the Brühl. Robert Schumann was also active in Leipzig music, having been invited by Felix Mendelssohn when the latter established Germany's first musical conservatoire in the city in 1843. Gustav Mahler was second conductor (working under Artur Nikisch) at the Leipzig Theater from June 1886 until May 1888, and achieved his first great recognition while there by completing and publishing Carl Maria von Weber's opera Die Drei Pintos, and Mahler also completed his own 1st Symphony while living there.

This conservatoire is today the University of Music and Theatre. A broad range of subjects can be studied, both artistic and teacher training, in all orchestral instruments, voice, interpretation, coaching, piano chamber music, orchestral conducting, choir conducting and musical composition. Musical styles include jazz, popular music, musicals, early music and church music. The drama departments teach acting and dramaturgy. Advanced students may, after a test, stand in for members of the Gewandhaus Orchestra. As at 2006, approximately 900 students were enrolled at the school.

The city's musical tradition is also reflected in the worldwide fame of the Leipzig Gewandhaus Orchestra and the choir of the St. Thomas Church.

Leipzig is known for its independent music scene and subcultural events. Its most famous indie-labels are Moon Harbour Recordings and Kann Records.

As for contemporary music, Leipzig has for more than 10 years been home to the world's largest electronic music festival, the annual Wave-Gotik-Treffen (WGT), where thousands of electro fans from across Europe gather in the early summer.

The city’s contemporary arts highlight is the Neo Rauch retrospective opening in April 2010 at the Leipzig Museum of Fine Arts. This is a show devoted to the father of the New Leipzig School of artists. According to the New York Times, this scene "has been the toast of the contemporary art world" in the past decade. Further there are eleven galleries in the so-called Spinnerei, a former cotton mill that attracts all kinds of independent artists.
