I have it, and it's good. Not as pre-digested as Mamady's videos, so it's more a matter of listen and learn. The biggest issue for me was that Bolokada plays the solos without accompaniment at a slow tempo (which is great), but there is no pulse reference. In some places, it's easy to get lost and perceive a solo phrase incorrectly relative to the pulse. But all these phrases also appear in the ensemble section, so it's not a big deal; you can feel how each phrase sits against the pulse quite easily there.
It's definitely one of the good instructional videos out there; I recommend it.
