Eight years after Blue Maqams, Anouar Brahem returns with a poignant project, titled after a line of verse by poet Mahmoud Darwish, which asks “Where should the birds fly, after the last sky?” Graceful chamber pieces for oud, cello, piano and bass subtly address the metaphysical question and it’s broad resonances in a troubled time. While drawing upon the traditional modes of Arab music, Brahem has consistently sought to engage with the wider world, too, and found inspiration in many sources from different cultures. Bassist Dave Holland and pianist Django Bates are again part of the Tunisian oud master’s international quartet, joined now by cellist Anja Lechner.
