my general impression, unscientific but based on hard won experience, is that through the album discography of Parliament/Funkadelic/George Clinton/etc there prevails an average of two good tracks per LP
there is the Single/the one everybody knows, and the One Other Good One
i bought One Nation Under A Groove in the very early Eighties from a store near Wardour Street that was full of discounted lps from Germany or the U.S. (i'm guessing, because my copy of ONUaG was a cut-out, the corner snipped off, which I'd never seen before, and is US-only-practice, right?)
i had heard "One Nation Under A Groove" the single and imagined the whole album would be like that i.e. glorious
imagine my disappointment!
imagine the consternation, further, on playing the giveaway free 7 inch single which had a live version of "Maggot Brain" on it. (you gotta realise, this is before the internet, the knowledge was not out there, not at all-- i had no idea that Funkadelic had been a black rock group. also, this is when i was a doctrinaire post-punker who thought gtr solos were verboten)
anyway, this is the One Other Good One on One Nation Under A Groove
