Last Leaf Danish String Quartet ECM Records CD   The Danish String Quartet is best known for their insightful interpretations of classical and contemporary repertoire. For instance, a 2016 CD for ECM Records presented early works by Ades, Norgard, and Abrahamsen to widespread acclaim. However, back in 2014, the quartet had a best seller on Da Capo, Wood Works, that consisted of arrangements by its members of Scandinavian folk tunes. In 2017 they released Last Leaf, another album of these arrangements and original compositions for ECM.   Last Leaf is in many ways even more successful than Wood Works. The
