Bulgarian-born Dobrinka Tabakova’s Such Different Paths (2007-08) was the afternoon’s discovery. Scored for string septet, Yabakova’s riveting eighteen-minute score melds repetitive minimalism and folk influences with the ancient sound of a viol consort, and the spiritual raptness of Arvo Pärt and Henryk Górecki. The music alternates rapid episodes with more reflective and contemplative sections. At times, the musicians play the same figurations out of sync, yet Tabakova’s sonic landscape is entrancing and beautiful. Cellists Blake-Anthony Johnson and James Churchill carried the score’s darker, more soulful moments with fine ensemble contributions by violinists Jonathan Chern and Brendon Elliot, violists Spencer Ingersol and Yuan Qi, and bass Douglas Aliano.
