Thanks to Rott's friends, some of his music manuscripts have survived in the music collection of Vienna's national library. This includes Rott's "Symphony in E major", and sketches for a second Symphony that was never finished. The completed symphony is remarkable in the way it anticipates some of Mahler's musical characteristics. In particular, the third movement prefigures the second movement of Mahler's First Symphony. The Finale includes references to Brahms's First Symphony. Mahler also spoke well of Rott's Lieder, of which all eight surviving complete songs have been performed in concert since 2002 and four sung by Dominik Wörner were recorded in 2009 on the Ars label. We also know of a "Sextet", which Mahler never heard and has also been lost. In his last years, Rott wrote a lot of music, only to destroy what he wrote soon after writing it, saying it was worthless.
