The Project

Early years

Wolkenpark began as a duo project by trumpet player Kriz Flew and sound designer/composer Mehdi Khansari back in the 1990s. Both grew up in a suburb of Zurich and began making music together by jamming and producing in Kriz’s bedroom. Mehdi used an ironing board as a keyboard stand for his Roland Alpha Juno 2, while Kriz recorded MIDI on his Atari 1040 computer. Trumpet cuts had to be recorded live, and the master was captured on a Casio DAT recorder, as 4-track tape recorders were unaffordable at that time. Despite these limitations, they achieved some success and won prizes in local competitions.

After leaving their parents’ homes, Mehdi pursued a career as a film composer in London, while Kriz stayed in Switzerland to study at the Swiss Jazz School in Berne. He also built up a recording studio ( and gained a reputation as a studio and session musician, working with musicals and numerous bands of all styles.

The duo

Several decades later in 2009, Mehdi had returned from London back to Zurich, their ways crossed again. Still having the same musical heroes, they decided to follow their own vision of an electronic, danceable, live emerging music which in this combination was never made and heard before.
In the beginning they struggled with hardware problems, laptops and interfaces had terrible latencies. But the constant search for better workflows and massive improvements of the soft- and hardware industry finally let them do what became Wolkenpark’s trademark: live improvised electronic music with a jazzy flavor and an impressive musical space.

As «Wolkenpark» they won the «Nightclub-City Original Song Contest» at Indaba with «Frappantine» and their Track «Cheerful Waiting Room» was elected for the Christie’s Lounge at the exhibition Art Basel in Miami and «Sparkling Water» got a 3rd price at «HOFA Production & Song Contest 2018» (listen to the tracks on this website).

Since Mehdi retired as live perfomer in 2018, they continue as jamming studio project.

The trio

In summer 2018 Kriz was invited to do some live gigs and took the opportunity to expand Wolkenpark to a trio featuring the extraordinary Jean-Pierre Schaller on electric bass and Andy Brugger on drums. Since 2016 they worked together with Andys electric jazz combo «Tanga Zoo». In Spring 2019 Wolkenpark played live on tour for the first time as a trio, visiting several cities in Switzerland. A second tour to Russia in spring 2020 had to be canceled because of the outbreak of the Corona pandemy.

The quartet

In June 2020 the trio had a session with exceptional pianist and keyboard player Julien Boss from Lausanne, which was so fruitful, that the band decided to continue as a quartet. After several rehearsal sessions they started recording material for their first release as a quartet in January 2021.

During 2022 several singles were released and on 12. 12. 2022 the first album «Wizard Wisdom» appeared on CD (and digital distribution) featuring two tracks with special guest Rootwords on rap and spoken word.

A new drummer

Due to different views regarding the future development of the band, Andy Brugger left Wolkenpark in spring 2023.
With Johan Wermeille Wolkenpark found a new drummer who immediately fit into the concept of the band.

In June 2023 the band spent again some days in the studio recording new material of which a first selection was finally released on 6./7. April 2024 as EP «Vagues (EP)». The sound became stronger, driving and more accessable without loosing experimental soundscapes and heavy brass stacks. The release of the full album with the same name «Vagues» (french for «Waves») is planned for October 2024.
