Bola's music aggressively melds sheer force of spirit with a sound not often heard by ears outside the remote Upper East Region of Ghana. His bold fury stems from the kologo, a two-stringed lute with a calabash gourd resonator and Frafra-language vocals, emitted in raspy bursts. This is some of the most distinct and dynamic music to come out of Ghana since the emergence of hiplife music in the mid-90s. Volume 7, which came out in 2008, is just one entry in a brilliant series of recordings Bola has released on CD and cassette.
