On Black Focus, Yussef Kamaal frame jazz inside the bass-saturated, pirate radio broadcasts of London. Taking inspiration from the anything-goes spirit of ‘70s jazz-funk, on albums by Herbie Hancock or the Mahavishnu Orchestra, it’s a loose template with plenty of room to experiment. The pair, made up of Yussef Dayes and Kamaal Williams (aka Henry Wu), have had little in the way of formal training. Instead, their musical tastes – and approach to playing – are indebted to Thelonious Monk’s piano as much as the drum programming of Kaidi Tatham.
