First of all, I'm not sure if there's a general consensus amongst historians that he changed the course of funk music.
And if he did, so what?
more bounce is a pivotal song in funk history
between that song and prince's keyboard/one man sex funk, that pushed the genre forward in2 the 80's

Second, Vaughn made a roller skate jam while more bounce was about....bouncing checks...i dont believe it was a response to roll bounce...that wasn't pfunk's style..those dude's had their own lane and wasn't copying from no one..

The person responsible for More Bounce wasn't Roger or Bootsy as the previous folks are saying....the person responsible for More Bounce's eclectic sound was..................George Clinton


Here's Shock G telling the story:

Okay, and while we’re at it, one more juicy little-known gem about the man: He’s responsible for the rhythm arrangement of “More Bounce to the Ounce” by Zapp(!!) Yes, George Clinton, in a little bit of a fluke, a little studio savvy, and a bit of luck, actually gave Roger that sound, that formula that Roger went on to use on his next 3 follow-up singles; “I Can Make You Dance”, “So Ruff, So Tuff”, and “Dance Floor”, That chunky stutter bass against the thick handclap? Zapp & Roger’s signature sound and main money maker? It was a George Clinton creation. (Doh!)

Very true. That sound is the result of George cutting a 2-foot long piece out of the 2-inch multi tape, flipping it around backwards, looping it to itself, and then slowing it down to the current speed of “More Bounce”. Apparently, Roger’s original groove was faster and a lot busier. They said it was in a vein like his “Heard it through the Grapevine” song: fast and choppy with a busy chord progression, and the bass was all over the place, an elaborate melody.

George, who was producing Roger’s first album for his new Uncle Jam label that year (which is another fascinating story: how the crazy older brother Larry Troutman sneak signed the group to Warner Bros. behind George’s back while he and Bootsy left the studio to get food. Yes, the same crazy brother who shot Roger dead 10 years later.)

Anywayz, earlier that day, while Zapp was still set to be the first new act on George’s label, George got concerned that Roger didn’t have anything they could use as a single yet, and that he needed something simpler then what he had heard so far, and that’s when he performed the tape trick.

The new slower piece in reverse created the rhythm and melody that became the infamous “More Bounce” kick-drum and synth-bass “B-B-Bomp CLAP-Bomp-Bomp” arrangement. With a smile George said “That’s all ya need right there. Just build the song around that”, and the rest became that beast of a record. If you listen closely, you can still hear the backwards bass & drums underneath; that was the first thing they started with, and then began overdubbing more tracks on a second 2-inch machine.

They told me that Roger also had about 10-times the lyric content he wound up using and that George convinced him to eliminate most of it and just keep repeating “mooore boooounce” they way he did. I was told this first hand by Boogie the bass player and Gary Shider, who were both also there that day.

And speaking of George’s Zen-like integrity; get this:
-after he had a verbal agreement from Roger and had been grooming him for months to be the first release on the new Uncle Jam label, and also after producing a good portion of his album so far, (including literally creating “More Bounce” for him), after all that, when George returned and learned that a Warner rep had showed up, went in the back room with Larry and Roger, talked him out of signing with George’s label in 5 minutes they said, and signed him directly to Warner–

They said George looked at them with disappointed eyes that said “Really?” looked down at the ground for a second, shook his head no, shrugged and said “Well, so much for that”, and turned around and walked out the studio.

The remaining P-Funk cats walked out after George, and I think they said Bootsy was the only one who stayed behind to help finish producing it, which is why Bootsy’s name appeared in the credit.

But yeah, George gave that classic song it’s essence as well as named the group “Zapp.” He never sued or spoke about it again, he just let it go, but I heard he was sad and heartbroken by it, as he had a friendship building with Roger prior to that incident.
