1971 and Black America was luxuriating in the soft soul of the O'Jays, the Temptations had just left behind their flirtation with psychedelia, James Brown was explaining Soul Power, Sly & the Family Stone were having a Family Affair, and Marvin Gaye was asking 'What's Going On'.

In their own inimitable way, Funkadelic were laying down their own statement about the ecology of the planet in the opening of lead and title track 'Maggot Brain', turning it into an elegy for the Earth in the ensuing heart-wrenching extended Eddie Hazel guitar solo - one of the most radical records of the period.

The album also spawned two Top 50 singles with the usual Funkadelic wry observational humour of 'You And Your Folks, Me And My Folks' and 'Can You Get To That'. And just in case you think things have normalised, the set closes with nine minutes of the chaotic sound collage 'Wars Of Armageddon'.
