The redoubtable Red Hot Aids charity has already released a tribute to fallen Nigerian legend Fela Kuti, 2002's Red Hot + Riot. This sequel, timed for what would have been Fela's 75th birthday, veers further from the master's Afrobeat template, principally via young African acts such as South African house producer Spoek Mathambo (on Zombie) and Kenyan hip-hop troupe Just a Band (on Gentleman). The results are erratic – 15 minutes of US rockers My Morning Jacket lost in Trouble Sleep is a yawn – but the Kronos Quartet pull off a reflective, chamber version of Sorrow Tears and Blood, and Fela's acute social commentary resonates throughout. A worthy homage.
