Rare and Unreleased 1971-1998 is a collection of never-heard and hard-to-find works by Swiss music pioneer and synth super wizard Bruno Spoerri. It gives a fascinating glimpse into Bruno Spoerri’s incredibly inventive repertoire, collecting tracks from projects as diverse as commissioned music for trade fairs, the Swiss railroads, or the union of Swiss cheese makers(!), soundtracks for TV shows about ecology, live synth improvisations at Montreux Jazz Festival, and sound installations for art exhibitions. Always the adventurer, Spoerri records a pneumatic drill for the irresistible electronic bossa of Konzert für SIG-Pressluftwerkzeuge, mixes train sounds and the EMS Synthi-100 for the joyful lo-fi funk of Rollin’, lets overheating synthesizers take a life of their own to create the sci-fi ambient of Waves of Montreux, and works with bees, pigs andvarious birds for the environmental music bliss of Rhythm’ n Bees and Birds of Cochin. Synthzerlandrejoice, it’s time for another captivating journey of sound exploration on Planet Spoerri!
