Optiv & CZA, who are known for their work behind Cause 4 Concern, keep making music as a duo. Almost every year the guys deliver something new, and this month will be marked by a new single on their home label C4C Recordings! Daring, powerful and groovy tracks, going under the titles Cell Dweller and Pitch Funk, will see the light of day on 16th December. Hopefully, there will shortly be an announcement of the recently promised album… 😉
