Thomas Demenga was born in 1954, in Berne Switzerland, preceding his brother Patrick into the world by eight years. (Patrick is also a cellist, and they are world renowned for their performances as a duo.) Thomas was already established as a soloist and a chamber musician before he began to compose music, writing his first piece at the age of 30 in 1984. In 1991 he won First Prize at the Tribune International des compositeurs in Paris for his composition "Solo per due".
Thomas Demenga studied with Walter Grimmer, Antonio Janigro, Leonard Rose and Mstislav Rostropovich, amongst others, and received his chamber music education at the Juilliard School. Successes at competitions in Genf and New York launched his international career.
Thomas Demenga's versatility is also manifested in his work as composer and teacher (he continues to hold a post at the Basel Music Academy). He is interested in music from all eras, and enjoys mixing widely varied selections in his concerts. He has made a series of recordings for ECM exemplifying this approach, with Bach's cello suites coupled with pieces by Heinz Holliger, Elliott Carter, Sandor Veress and B.A. Zimmermann. Thomas Demenga's Bach/Carter recording (ECM New Series 1391) was awarded the Quarterly Prize of the German Record Critics.
Demenga travels widely, giving master classes and appearing in cello congresses around the world. He is a well-known pedagogue, and has been instrumental in the training of many professional cellists.
