Ahmed Gallab is a musical nomad. On his fourth album, the London-born musician (best known as Sinkane) braids Afro-pop arrangements, Tropicália percussion, dub rhythms, country pedal steel and his understated R&B voice into a technicolor knot. Gallab doesn't stick genres into songs so much as he inhabits each one, however briefly: He finds numbing love above a Hammond organ on ''Hold Tight'' and lounges underneath funk horns on ''How We Be''). On ''Son,'' he struggles to define his roots through his Sudanese father. ''I will not forget where I came from,'' he sings, simply, as if through all these eclectic detours he's just trying to find a way home.
