BBC Radio 4 or some well-recorded BBC Radio drama. Then one of Trevor Nelson's 'Rhythm Nation' programmes from BBC iPlayer for a mix of soul and reggae etc.
Black Uhuru's 'Dub Factor' album, XTC's 'English Settlement' (probably 'Fly on the Wall'), the 12" extended mix of John Martyn's 'Johnny Too Bad' from 1981, Blur 'Song2', Small Faces 'Lazy Sunday Afternoon' (ah!), Caravan 'In The Land Of Grey & Pink' (whole of 'side 2') and more.
