The grand old man of Finnish Jazz, Eero Koivistoinen, has not kept still in his old age. Far from that, he's played with rappers from the younger generation, Argentinian tango singers or The Eero Koivistoinen Quartet, onto its 10th year in existence. 'Diversity' presents, as the title implies, a diverse selection of Koivistoinen's latest compositions plus a striking interpretation of the timeless Thelonius Monk classic 'Played Twice', here performed by the duo of Koivistoinen and pianist Tuomarila.
