A big although late thanks for these two excellent recordings. They are excellent technically speaking in terms of sound quality. But they are also very interesting from the artistical point of view.
I don't remember the other recordings of the dawr and I don't have much time to check, but I have the impression that this is the longest take we've ever had of it, at least by 'abdi-l-hay, if not in absolute terms (I have counted no less than four or five 'aghsan). And it is particularly tasteful owing to the obvious playful mood that characterises it and that is noticeable right from the madhhab with the sudden change of tempo in the middle of it. Other signs can be easily spotted through the various 'aghsan such as his playing with the words and syllables (see for instance tira- tira'ili).
The mawwal is also quite peculiar with its sort of staccato mode whereby words and syllables are rattled in short spells, which epitomises the so-called discontinuity aesthetics typical of 'abdi-l-hay style. This is all the more remarkable by the way it is reflected/translated in the hesitant and rather minimalistic play of the accompanying musicians.
