The association between Ulrich Mitzlaff and Miguel Mira promises an unforeseeable sound meeting. The specific, personal and different ways of their distinguished expression is the base for their very dynamic and interactive music. They create sounds where the improvisation moves with great fluency between the establishing of textures and abstract musical ideas and the switching in the musical discourse to singular, rhythmic and melodic affirmations. They construct the sonar explorations using the characteristics of their instruments just like a simple acoustic and global sound resource. Ulrich Mitzlaff formed prolific alliances with some of the most relevant musicians of the experimental music in Portugal, Carlos “Zingaro”, Nuno Rebelo, Carlos Santos e Carlos Bechegas. Miguel Mira has met with his bands all kinds of currents in the field of jazz, from fusion to improvisation with projects like the Rodrigo Amado Motion Trio and Rive Gauche and is playing concerts with Carlos “Zingaro”, Rodrigo Amado and Scott Fields
