Mutter is best known for her rich tone and her impassioned and exciting performances of the classic violin repertory, but she has also been instrumental in commissioning and performing new works for the violin. Among the composers she has worked with are Wolfgang Rihm
, Sebastian Currier
, Norbert Moret
, Witold Lutoslawski
, and Krzysztof Penderecki
. Both before and, for a time, after Mutter's marriage to conductor André Previn
in 2002, the pair performed and recorded together frequently. In September 2006, the couple quietly announced their divorce, and in October 2006 Mutter announced that she would be retiring from the concert stage on her 45th birthday in June 2008. She later stated that this was a misinterpretation, and in 2011 was still appearing in concert, premiering Lichtes Spiel by Rihm
, and making recital tours. Mutter also devotes time to her foundation fostering exceptional young musicians.
