Vietnam, ecological worries and poverty and suffering inspired the lyrics in Marvin Gaye's 1971 album What's Going On. Written as a song cycle from the point of view of a war Vet returning home, it was inspired in part by the letters he was receiving from his brother from Vietnam and from his own questions following the 1965 Watts riots. The Nu Civilization Orchestra is performing their version of the album at the London Jazz Festival tomorrow. Matthew Sweet is joined by jazz journalist Kevin Le Gendre, musician Gary Crosby, Dr Althea Legal-Miller - Senior Lecturer in American History & Culture at Canterbury Christ Church university and poet Roy McFarlane

The Nu Civilization Orchestra, founded by Gary Crosby, perform their version of the album at the London Jazz Festival at the Queen Elizabeth Hall, Southbank Centre 18th November @7.30pm, with subsequent dates in Birmingham, Liverpool & Canterbury.

You can hear a host of programmes featuring performers from the London Jazz Festival on BBC Radio 3 including a special Jazz Through the Night.
