The son of Peter Rummel, professor of law, grew up in Linz, where he went to primary school and graduated from Akademisches Gymnasium, where he received a Classical education, with highest marks in 1992.

After early harpsichord and piano lessons from Helga Schiff-Riemann, he started to learn the cello in 1982 from Wilfried Tachezi at what is today the Anton Bruckner Private University for Music, Drama, and Dance.

Rummel has given countless world and national premieres of works, amongst which Graham Whettam's "Concerto Drammatico“ (2000, USA) and the solo cello part in Thomas Daniel Schlee's sacred opera "Ich, Hiob" (2007, Ossiach[2]).

In recent years, Rummel has been increasingly emphasizing his performances of the cycle of the Solo Cello Suites by Johann Sebastian Bach and projects like his own arrangement of Franz Schubert's song cycle “Winterreise”, which he is performing with pianist Norman Shetler and actors such as August Zirner[3] and Xaver Hutter.

For the most important collections by David Popper, Friedrich Grützmacher and Jean-Louis Duport, Rummel wrote text volumes which are included in the editions.
