If you are willing to be patient Folila offers more surprises than you’d guess, flourishing on repeated plays.
Why did you write a review for people who'd "pass on the chance to even briefly listen to a West African blues act"? What's the music like? Does it work as an album? I'd also say that the featured artists are a lot more obvious than you suggest.
Decent album. Not as good as their previous two, but arguably up there with Sou Ni Tile and Wati.
