After Cobain was murdered, I hypothesize that Grohl was approached by by TPTB and made an offer he couldn't refuse. He claims to have written and recorded the first Foo Fighters album on his own. Does anyone buy that shit?
The psyop is that music is a huge part of bread and circuses and they wanted to capture as many sheeple as possible. Dave Grohl was a perfect opportunity to do this.
He may be a fraud and all that but it's absolutely not unbelievable that he wrote and recorded all that stuff. He had the money at the time. And I can barely pay guitar and I've recorded several of my songs. Plus the album doesn't even sound all that good
Do I believe it can be done, sure. Do I think Dave Grohl did it? Nope.
