Norwegian bassist and composer Mats Eilertsen has a special talent for uniting heterogeneous elements, eliciting deep and touching resonances from them, and letting them sound like a family of beautiful and complementary voices. An impressive example was his recent Memorabilia, a new work commissioned by this year’s Jazz Festival in Trondheim - the town of Eilertsen’s birth - for his trio with Harmen Fraanje (p) and Thomas Strønen (dr) together with the vocals/violin of Trio Mediæval.
