SPECTRA was founded in 1993. The core of this chamber ensemble constists of eight inspired musicians, working intensively together for over a decade, thus creating a unique sound and musical coherence. The ensemble contributes impassionedly to the promotion of Flemish contemporary composers in the (inter)national music scene.

SPECTRA creates many commissions in continuous dialogue with referential pieces, using a wide variety of presentational forms such as concerts, happenings, musical theatre and multi-media events.
Its undogmatic programmes and idiosyncratic performances are highly appraised by organisers and creative artists, hence its collaboration with composers such as Luca Francesconi, Stefano Gervasoni and Nicolaus A. Huber.
SPECTRA performed in and outside Europe at festivals such as Ars Musica (B), Transit (B), Festival Musica Nova (Brazil), November Music Festival (NL/B/D), Musica Sacra (NL), OEROL Festival (NL), Huddersfield Contemporary Music Festival (GB), the Traiettorie Festival (I), the Biennale Venezia (It) and the World Music Days 2010 Sydney (Aus).
