Testing rather than jettisoning conventions, Tetterapadequ is a young European band that’s genuinely exploratory, willing to test approaches from a jazz-based rhythmic concentration to solo interludes and even a period of extended silence. It consists of two Italians (tenor saxophonist Daniele Martini and pianist Giovanni di Domenico) and two Portuguese (bassist Gonçalo Almeida and drummer João Lobo), but the key geographical point is the Netherlands. The band’s name is a near-anagram of De Patter Quartet, named for a favourite jazz club the quartet attended while students at a Dutch conservatory. Each is a player of substance, with Martini possessing a marked vocal force and rhythmic imagination and Di Domenico, showing a marked classicism that extends to Satie-like reflections. Almeida presses extended techniques while Lobo adds consistent interest with alternately dense and sparse sonic fields. Tetterapadequ’s eclectic wit suggests the Dutch scene in which they met, while the textures may recall the early work of Giorgio Gaslini, thanks largely to Di Domenico’s ironic classicism.
