The brutal truth why Zimdancehall stables have the tendency to also manage upcoming artists is because they produce, record, mix & master their music for free when they discover them.
So they kinda think the only they can be compensated for all that initial effort is by giving an artist a management contract on top of a production deal or record contract.
I know this sounds retarded but this is Zimbabwe we are talking about. Things are rough for ghetto youths on the come up.
