Entitled "Manifesto," the new album of the Luxembourg-based contemporary jazz trio around the drummer Jeff Herr consists of seven original songs and a surprising cover of Randy Newman's "Same girl." It ensures the continuity of the previous album, "Layer Cake," of the oscillation between structured compositions and free improvisations, as well as of the contrast between the acoustic sound and contemporary interpretation. This time, however, the trio has been joined on several songs by the American guitarist Adam Rogers, known for his work in the modern jazz idiom and his numerous collaborations with musicians such as Norah Jones, Ravi Coltrane, and Marcus Miller. His guitar playing, rooted in the acoustic jazz tradition and influenced by Pat Martino, George Benson, and Wes Montgomery, provides the Jeff Herr Corporation with a unique aspect and a new, intriguing sound.
