Jefferson started to play the mandolin at age 11. The crystal clear sound similar to a “star rain” took him instantly away to another world.
Mainly self-taught, his curiosity rapidly led him to discover fabulous musicians from the Bluegrass scene whom he drew an endless inspiration from for many years.
One of his most significant and early collaboration was with his brother Steve with whom he played since the very beginning (Louvat Bros-Award 2012 for the most innovative European Bluegrass band received at the European World Of Bluegrass in the Netherlands).
Two friends and legendary musicians, violinist Byron Berline and banjoist Bill Keith played a crucial role in his access to the US scene back in the 90’s.
From intimate concerts, through renowned festivals and mythic stages such as the Grand Ole Opry in Nashville, the International Bluegrass Music Association (IBMA), he performed across Northern America and Europe.
The virtuosity acquired with the Bluegrass school combined to his sensitivity inherited from his Hungarian roots helped him to develop a subtle, authentic and dynamic style of play.
Now, Jefferson plays in Szabadsag, a duet with french violinist Ariane Cohen-Adad, which combines Bluegrass and Klezmer/Yiddish music.
Together they have been playing extensively in Belgium and France as well as abroad including Bulgaria, Sweden, Hungary, America and Japan.
Their latest album « Ellis Island » has been nominated at the Octave de la Musique in the World Music category in 2021.
Jefferson is regularly solicited to take part to diverse projects, music camps, workshops and recording sessions.
