Besides being regular guests at some of the best known Hungarian jazz venues, they made their advances on the international scene. In June 2004, the quartet played at the Peter & Paul Festival in St.Petersburg at the personal invitation of one of Russia’s best known jazzmen, pianist Andrei Kondakov.

In 2005, the Bolla Quartet performed to standing ovation at Amsterdam’s most presigous jazz-venue, the Bimhuis, and also played in Belgium, Austria, Germany and Slovakia.

The Bolla Quartet scooped both the Grand Prix and the Prix du Public at the 2005 Avignon Jazz Festival in France.
