Brecht Ameel (santoor, bouzouki, keys) and Bart Reekmans (percussion, brass) have been working on a repertoire in which etnic music and improvisation are the central concepts. Tired of the traditional guitar-bass-drums combination they decided to both choose an instrument they couldn’t play at all. They ended up with a heavily detuned santoor and some metal plates that served as a drum kit. In a deserted basement Razen make unusual instruments confront until they derail and make for a filmic sound trip in which Bohren & Der Club of Gore and Moondog meet. They've expanded their instrumentation to include still more instruments they don't know how to play (bouzouki, keyboards, horns), and have invited a handful of guests to contribute an even more impressive and bizarre arsenal of noisemakers, including bagpipe, chalumeau (a classical style recorder), sopranino (one of the smallest horns in the saxophone family), bass recorder, duduk (a Middle Eastern woodwind) and shenai (a North Indian oboe), and this is the result: a glorious, mysterious take on world music, dark and haunting, heavily percussive, cinematic, abstract and dramatic.
