The Nice - Five Bridges: The first real progressive rock album?

This week Tim did a monologue on Five Bridges by The Nice. Topics covered include: whether Five Bridges is the first stage in the development of the progressive rock "paradigm"; where the album stands in the band’s catalogue; how The Nice compares to ELP; and whether the dialectic between band and orchestra is successful. Also, why don’t bands get Arts Council grants any more? What does the band have to do with the philosophy of science? Was the introduction influenced by tantric sex? Was Lee Jackson a Maoist? How do you say “ars” without causing offence? And most importantly of all, what does Stumpy say?
