I've never spoken to LD to know his opinions whilst your implications about using other sources for inspiration was stressed by Hamaysian and his bassist and drummer for that matter. They clearly believe they are playing jazz even if it has little reference to any Black, American music. I repsect their choice to try to produce music which is original and different and concede that using Armenian influences will certainly add to picquant new flavour to the music. Fair play to them in this respect. The music is not for me though.
