A tuba playing jazz musician might have the right to describe his sound as unique – after all, tuba soloists in jazz are as rare as hen’s teeth. But when we describe Norwegian tuba player and composer Daniel Herskedal as unique, we’re not referring to his choice of horn. In the last few years this young musician has proved he has the facility, vision and musicianship to push the boundaries of his instrument, technically and sonically, further than anyone has done so. The result , as demonstrated by his new album ‘Slow Eastbound Train’, is a spellbind- ing and mesmerising sound worthy of a vast international audience.
