[1] In 1978 Strauch joined the ensemble intercontemporain,[1] a French chamber orchestra of 31 soloists founded in 1976 by Pierre Boulez.
In 1994, Strauch, along with composers Diogenes Rivas and Antonio Pileggi, founded the Festival Atempo[1] in Caracas, Venezuela.
[2] Strauch has performed, premiered and recorded many 20th century works by composers such as Iannis Xenakis, Luciano Berio, Bernd Alois Zimmermann and Olivier Messiaen.
Strauch gave the Parisian premiere of Time and Motion Study II by Brian Ferneyhough and Ritorno degli Snovidenia by Luciano Berio.
The ensemble intercontemporain commissioned a work for fifteen instruments, La Escalera del dragón (In memoriam Julio Cortázar), which was premiered in 2004.
