The Fertilizer festival, now in its third year, is a short, sharp blast of air from another planet (or, in this case Germany), with jazz, techno and even reggae. Joyosa, however, is not purely German - it unites the talents of trumpeter Markus Stockhausen and drummer Samuel Rohrer with Hungarian guitarist Ferenc Snetberger and Norwegian bassist Arild Andersen.

Stockhausen is a terrific classical player and one of the most celebrated interpreters of the work of his father, Karlheinz Stockhausen. Joyosa's repertoire is less intergalactic in scope than that of Stockhausen Sr, but Markus brings a cool elegance to every note, whether on piccolo trumpet, flugel or regular trumpet with Harmon mute, which he plays exuberantly on the band composition Virginia. This tune has a funky, gappy groove, reminiscent of Tutu-era Miles Davis, and a great platform for some spectacular bass-playing from Andersen.

Snetberger contributes thoughtful compositions such as Empathy, with its subtle melody and oud-like acoustic guitar improvisations, reminding us that Markus Stockhausen's CV includes a stint with Dhafer Youssef in addition to the great orchestras of Europe. His tune, Freund, rides the journey from melodic chamber jazz to free improvisation without self-consciousness. Throughout the set the acoustic and electronic sounds (including digital trickery on both bass and trumpet) were blended in a particularly clear mix by Norwegian sound engineer David Solhein.

Andersen is star of the show, contributing outrageously virtuosic bass lines and unexpected sounds to every number - empathetic, innovative and creatively disruptive by turn. His composition Hyperborean is a towering structure of layered and echoplexed solo basses, leading into a beautifully judged ensemble piece.
