She does the singing and it has nuance and an expressive beauty. The songs are what one might call Mid-Eastern jazz with an emphasis on song form, some songs being squarely in a very modern-ish ECM-like or otherwise jazz zone, with the Mid-Eastern tonal minor element coming to the fore or receding a bit depending on the song. The ensemble that accompanies her reinforces that two-world (or is it three?) sound via an eclectic mix of oud and violin, guitar, piano, acoustic bass and drums, with the addition of traditional percussionists, etc., from time to time. Some songs have a jazz-rock underpinning, some not, but all are quite interesting in their arrangements, in their song-ful-ness and in their vocal presence.
The result is a modern pan-Israeli-Palestinian music that has much charm and substance if one opens up to it. Fascinating and rewarding listening!
