He began his violin studies in Córdoba (Argentina) and in 1984 moved to Germany, where he studied at the Cologne University of Music with F. Maier. In 1985, he founded the Concerto Köln orchestra, and a year later he was invited by R. Goebel to participate with Musica Antiqua Köln, a world-renowned group in the field of baroque music. Over the next few years, an intense concert activity, also as a soloist and conductor, and around a hundred annual engagements, took him around the world. At the end of 1991 he was invited by the most important specialized directors from all over the world. In 1996 he created the instrumental group The Rare Fruits Council, whose recordings have always been praised and awarded.
In 2000 he founded La Barroca del Suquía Córdoba. With its ancient instruments, the orchestra is currently considered one of the best groups of its kind in Latin America, offering masterpieces of the Baroque repertoire in its original versions, never before performed on the American continent.
Since 1991 Kraemer has collaborated closely with J. Savall as the first violin of his orchestra Le Concert des Nations. Nominated by BBC Music Magazine in 2004 as one of the most prominent Baroque violinists of today, his discography comprises more than 40 titles.
