Guru, an undisputed legend, is back with a new label, a new producer and a new album. And guests include Jean Grae, Talib Kweli and, amazingly, Cypress Hill’s B.Real! Only, something’s not quite right. Guru still possesses the trademark vocal skills with which he made his name, but these are lost here amongst the underpowered, synthetic and, sometimes, scarily poor production. Filling the boots of Gangstarr"s other half, the awesome DJ Premier, is clearly a Herculean task, but surely new boy Solar could have done better.
