Imagine a cross between Xenakis, Pierre Boulez and Frank Zappa ... The raw energy of the first, the strangeness of the second iconoclastic and tight construction of the third ... Nervousness, electricity, power, breath, complexity into the microcosm that is the Walter Boudreau of L'odessée du soleil and of Demain les étoiles. Add irreverent complicity of the poet Raoul Duguay for Golgot (h) a.
