Underrated ? Come on man.
Naa I kinda get what he's saying, when people talk about their favourite atalakus and even artists themselves you'll rarely almost never hear Mboshi and Somono's names. It's always Bill, Tutu Callugi, Celeo, Ekokota, basically any atalaku from clan Wenge lol. I'd even put CNN on the underrated list, Somono whatever I think about him personally did influence some atalakus out there, cause there are some that sound similar to him with his style. Mboshi, Somono, and CNN did big stuff and defended QL well.
