"Gidon Kremer (born 1947) is a Latvian violinist and conductor. In 1980 he left the USSR and settled in Germany. Kremer is known for his wide-ranging repertoire, extending from Vivaldi and Bach to contemporary composers. He has championed the work of composers such as Ástor Piazzolla, George Enescu, Alban Berg, Philip Glass, Alfred Schnittke, Leonid Desyatnikov, Alexander Raskatov, Alexander Voustin, Lera Auerbach, Pēteris Vasks, Arvo Pärt, Roberto Carnevale and John Adams. Among the many composers who have dedicated works to him are Sofia Gubaidulina and Luigi Nono. His partners in performance include Valery Afanassiev, Martha Argerich, Oleg Maisenberg, Mischa Maisky, Yuri Bashmet and Vadim Sakharov. Kremer has numbered in his collection of antique violins a Guarneri del Gesù violin made in 1730; and the Antonio Stradivari violin of 1734 often referred to by its sobriquet, Baron Feititsch-Heermann. His current violin is a Nicolo Amati violin dating from 1641." http://en.wikipedia.org/wiki/Gidon_Kremer
