Malian desert blues group Tamikrest return for another blend of modern-era Tuareg, a traditional upbeat music of the nomadic people principally of the Sahara in North Africa.
The electric guitars and glossy production will not appeal to all fans of this tradition but nevertheless Chatma is an intriguing concept.
Translated as "sisters" Chatma is dedicated to the "courage of Tuareg women" and their role in the founding and survival of the culture.
There's plenty of variety to enjoy too.
Imanin Bas Zihoun is a catchy, sing-along affair while Adounia Tabard gives some acoustic relief.
Influences of dub, psychedelia, funk and prog-rock can also be heard, which will appeal to fans of the eclectic.
But whether this can be taken as a positive sign of the band's progressive streak or rather a move away from their roots to become more European-friendly is down to the listener.
