Below are two projects from duo Siedl/Cao with their electro-acoustic compositions.
New music for marxophone/zither and clarinet
Zicla is a project by duo Cao Thanh Lan (VN) – Gregor Siedl (AT) with electro-acoustic compositions and composed improvisations for prepared marxophone/zither, clarinet and electronics.
Clarinet and zither are commonly known for folk music across the globe. Using these two instruments in a new syntax evokes a familiar and at the same time foreign environment.
The clarinet’s composed pitch and noise structures interweave with particular sounds from the extended zither creating an unusual imaginary space, introspective moods, abstract microtonal dialogues and intriguing sound textures.
Parallel Asteroid connects experimental, acoustic and electronic sounds with the aesthetics of contemporary music. Their performance is a re-search into the relationship between electronic and organic sounds, creating abstract beauty when these worlds collide. Their music is a result of introspection and the trust to give in to the fragility of the moment where ideas crystalize into abstract shapes and textures. The musicians are the Vietnamese pianist and synthesizer player – Cao Thanh Lan and Gregor Siedl from Austria on saxophone, gamecalls and tubes.
