Indeed, there are very few artists today who take the time and make the effort to deliver such quality.
In my view, Lingala Music may be in danger of deterioration due to this phenomenom.
Most albums today are very hurriedly done, and a lot of attention and care is not put in teh effort, maybe due to the need to roll out as much quantity as possible to maximise on income and make as much money as possible.
Purists like Kester, Papa Wemba, Tabu Ley, and others as a dying breed.
