I’m beginning to seriously suspect Oklahoma’s history telling capacities. Let’s just say that it seems very reticent to tell a history about it’s non white residents. To say nothing of the long suppression of the 1921 Race Riots which destroyed Tulsa’s Black Wall Street (and the all black town of Greenwood), look at this site about an exhibit on Oklahoma Rock & Roll in the 60s and 70s. http://oklahomarock.com/oklahoma-rock-and-roll-1960s-1970s/
All these groups, and they don’t even mention The Gap Band (brothers Charlie, Ronnie, and Robbie Wilson) who were from Tulsa. Perhaps one wants to say that The Gap Band was more funk, which is true. But … I don’t know that it’s any less Rock than this piece (which is on the site) could also be called country . . .
Plus there’s a kind of funk sound to a lot of 60s, 70s Rock (since it is after all coming from the Blues). Check out this Leon Russell “Stranger in a Strange Land” (also on the site). You can hear the funk:
