Four fake birds sit - even pencil and black ink in front of pink-purple watercolor - on a twice bent branch. This is at the same time the crank that could mechanically elicit scratchy song from the wide-open bird beaks. Suppose the two-dimensionality of Paul Klee's "The Chirping Machine" were to dissolve and make room for the crank. What cannot work in the 1922 painting - often interpreted as a sound symbol of modernism - is solved by alto saxophonist Mark Weschenfelder's Zwitschermaschine with its powerful sound. The ensemble unites four wind instruments driven by a rhythm section. In an unorthodox way, the band's sound is determined by two flutes, which flicker, glitter, chirp alongside, with or in front of the saxophone, trombone, guitar and bass. Weschenfelder's compositions come across as compact, colorful, fast-paced and without simple launching pads for improvisational self-expression. The band's debut album, "System for Us," was released in 2019 on WhyPlayJazz and bundles seven individualists into a dense, shared sound from which small solos flash like light at times. Pleasantly powerful, unpretentious music.
