Parliament/Funkadelic?
Are you nuts!
Also, where's Earth Wind & Fire? The Isley Brothers? The Average White Band? Marvin Gaye? The Temptations? Isaac Hayes? Curtis Mayfield? Michael Jackson's "Off The Wall?" Slave? War? Barry White? George Duke? Grover Washington, Jr.? The Commodores? Rick James? Al Green?
C'mon!
You can't mention the 70's without those who put the "unk" in "FUNK!"
Lastly, I'm only 29. I'll be 30 on the 22nd of this month. I know a thing or two about the old school, white bands included.
No thing, tho'. It's just a Motor Booty Affair.
Ya dig?
As for Barry White, Rick James, George Duke, AWB, and Isaac Hayes, I will give you that they each had classic songs but I would argue that none of them had an album that could make a discussion of "best albums" of the 70's.
Talking Heads is another band that would make my list. Bob Marley and the Wailers had several (Burnin, Catch a Fire, Natty Dread, Exodus).
Grateful Dead "Workingman's Dead" is another possible.
