For Lullaby, Norwegian trumpeter Mathias Eick relies on the cohesion of a quartet composed of Kristjan Randalu on piano, Ole Morten Vagan on double bass, and Hans Hulbaekmo on drums, in a program that leverages the most adventurous qualities of his approach to improvisation. Throughout, the highly melodic music unfolds a sense of abandon, with the musicians gently floating between harmonies to generate collective dynamics within the song forms.
