As part of my homework before last night’s gig at the Scala I played Senegalese singer Cheikh Lo’s latest album Jamm over and over again, waiting for some of its tunes to lodge in my mind - waiting to be compelled rather than feel duty bound to play it again. But no, I just couldn't connect with it. There’s nothing ostensibly wrong with the thing: it’s brimming over with easy-going cheer and passion, it's beautifully played and sung, and it’s all wrapped up in that familiar crystal-clear production that producer Nick Gold is so adept at delivering (his recent work with AfroCubism being another perfect example). But something was missing.
