The ARTE Quartett was founded in 1995 by the saxophonists Beat Hofstetter, Sascha Armbruster, Andrea Formenti and Beat Kappeler.

Their musical style consists of contemporary music, jazz, and free improvisation. The four musicians have commissioned many works, often working collaboratively with a composer in developing a composition. The quartet has also arranged and composed original music which they often present at concerts with a thematic focus.

ARTE Quartett has performed concerts with Urs Leimgruber, Hans Feigenwinter, Terry Riley, Michael Riessler, Tim Berne, Fred Frith, Nick Didkovsky, Pierre Favre, Lucas Niggli and Rabih Abou-Khalil.

The quartet tours regularly, plays at various festivals and concert series, and has recorded with various national broadcast companies.
