Ensemble

Ensemble

Sonic Tracers are a group of musicians who share having an intensive engagement with transcultural music over many years. They have come together to further explore the boundaries of “trans-traditional” music practice.
 
The group is complemented by musicians from different disciplines and countries (who are not listed extensively here) who also share the desire to experiment, communicate, and learn.

Claudia van Hasselt

 Claudia van Hasselt regularly devotes herself to experimental art projects, e.g., in collaboration with French artist Saâdane Afif. In numerous engagements in opera productions and at festivals such as the Ruhrtriennale, Märzmusik Berlin, Konzerthaus Berlin, Staatsoper im Schillertheater, and Deutsche Oper Berlin, she has worked as a soloist with conductors such as Jonathan Stockhammer, Peter Eötvös, Manuel Nawri, and Titus Engel. Her extensive solo repertoire includes numerous world premieres, including works by Johannes Schöllhorn, Wolfgang von Schweinitz, Sergej Newski, Sarah Nemtsov, Wolfgang Rihm, Sofia Gubaidulina, Carola Bauckoldt, and Beat Furrer.

In 2013, she founded FrauVonDa///storytelling in music as artistic director with director Lotte Greschik, audio-visual artist Nicolas Wiese, and costume designer Marianne Heide. Crossing genre boundaries, they illuminate historical material from the perspective of individual destinies and present it in the context of contemporary music. This results in original mini-operas that are collages of historical and contemporary material.

In 2016, she began researching traditional songs, initially focusing on the common roots of Persian and Western musical traditions in the context of contemporary music. She pays particular attention to the influence of Persian tradition on Western singing and its ornamentation. In her artistic expression and contemporary commissioned compositions, she focuses on a musical-experimental space between both musical traditions and their musical thought structures.

In the same year, Claudia van Hasselt founded the FemaleSingersUnited network.

It is expressly dedicated to the collaboration of traditional singers worldwide with German/European singers and musicians in the context of contemporary music. The network strives for intensive professional and artistic exchange.

The focus is on the intertwining of cultural spaces and musical traditions in an individual, experimental sound language between improvisational and composed works. The trans-traditional artistic product, adapted to the circumstances, is based on the deep structures of the respective cultures and combines them in contemporary formats. The first artistic product of this collaboration is the Persian-German music theater ORNAMENT, which premiered in November 2019. This work was continued in 2020 with the project ‘mimesis::imitatio’.

Bakr Khleifi

Bakr Khleifi was born in Jerusalem and began learning music at an early age. At the age of six, he began learning the oud and studied with the renowned oud player Ahmad al-Khatib. Over the next ten years, he studied with various oud players such as Simon Shaheen and Samir Joubran from the Joubran Trio.

At the age of 15, he began learning the double bass and within a year became a member of Daniel Barenboim and Edward Said’s West Eastern Divan Orchestra. Bakr holds a bachelor’s degree in world music with a focus on the oud from the University of Gothenburg in Sweden. He also holds a master’s degree in double bass from the Buchmann-Mehta School of Music in Tel Aviv.

Throughout his career, Bakr has performed in numerous venues as both a solo oud player and double bassist. He was a member of the West Eastern Divan Orchestra for six years and has performed at some of the world’s most prestigious venues, including Carnegie Hall, Teatro La Scala, the Berlin Philharmonic, Boulez Saal, and the Royal Albert Hall, to name a few. As an oud player, he has performed many times in his native Palestine, as well as in Vienna, Berlin, Seville, Gothenburg, and other cities in Europe and the United States.

Bakr was a teacher at the Barenboim-Said Foundation in Ramallah, where he taught music appreciation and music theory and instructed young students in orchestral repertoire. Bakr’s musical identity is diverse, as he had to combine learning both the maqam system and the Western classical tradition from early childhood. He firmly believes that one can achieve perfection in a particular musical genre while remaining open and receptive to other musical disciplines. In the field of new music, he has played with the Ensemble Extrakte, among others.
