The Eastern Boundary Quartet is a collaborative quartet featuring Hungarian master musicians, drummer Balázs Bágyi and wind player Mihály Borbély, and the long-standing bass/piano partnership of New York City bassist Joe Fonda and pianist Michael Jefry Stevens (co-leaders of the Fonda/Stevens Group and Conference Call). Since 2007 the quartet has toured Europe and the United States numerous times, and has released four CDs.

The group uses Hungarian folk rhythms and melodies in combination with jazz harmonies and rhythms to form an original, “hybrid” improvised music. They performs original music by all members of the group. The band was formed with the aim of connecting two worlds of the jazz scene today. This unique collaboration is a mixture of avant-garde jazz and ethno-music from Hungary, forming a cultural bridge between the USA and Eastern Europe. This bridge is made of talent, respect, brotherhood and friendship, built by the common language of jazz and improvised music.
