Jazz goes Rock goes Prog goes Electronics

Yabbalaga is the name of the new project by Cologne saxophonist Stephan Mattner. Together with bassist Sebastian Räther and drummer Ralf Gessler, he presents eight exciting pieces on Creatures.

Sometimes more jazzy, then more inclined to rock again, the prog rock-oriented track „The Diva“ also sets new standards in this metier with this instrumentation, electro beats and house soundscapes round off the groovy trip through Yabbalaga’s music world.

The loops were recorded in advance with flute, clarinet and soprano sax, partly edited and played back to live music. This creates a powerful construct which can go hand in hand with coincidences in a clear structure.

„… exciting concept …“

„…Not only does it create attractive tonal friction between the acoustic instruments and digital phrases, but also random shadows and overlays of form and structure of the pieces as well as those within them Mixtures of contemporary music to be heard Jazz, loud prog rock or swirling techno. That the result is neither simple nor simpel sounds also has to do with the fact that Räther and Gessler groove together wonderfully and Mattner on the tenor saxophone is a great inventor of really heartwarming melodies …“

„…Das alles erzeugt mächtig Atmosphäre, wodurch diese Platte auch echte Soundtrack-Qualität aufweist…“

„Film noire aesthetic with a good dose of retro-futurism.“
