Kojo Antwi is a very famous artist in Ghana, but probably unheard of anywhere else. This is because he is mainly know for his music sang in Twi, many people feel he is the best musician in the language of Twi. Many of his songs are love songs also, the genera is a little hard to nail down with influences from reggae, and pop, some might call it Twi-Pop.
Regardless the music is easy listening and pleasant on the ears. The videos are usually fun as well.
