During his time as a concert guitarist, he won prizes at various international competitions, performed as a soloist with outstanding orchestras (including the Carl Philipp Emanuel Bach Chamber Orchestra, Berlin) and travelled internationally for concerts to India, Brazil, the USA, Russia and across European. Various well-known composers (including Carlo Domeniconi and Jaime Zenamon) dedicated compositions to him and entrusted him with the premiere performance of their works.

Thomas Fellow ended his classical career in 1992 with a successful concert in the Philharmonie Berlin. Since then he has concentrated on his own music and on selected projects.
