Dave Grohl explains why he directed a documentary, besides the fact that he is Dave Grohl and he can

Dave Grohl is just like all the other obsessive music nerds out there, except he was a part of two of the most popular rock bands of all time and so he has a lot more money. That money not only affords him the ability to indulge in that obsession by collecting expensive things, like the console from California's Sound City Studios—long considered the holy grail of analog recording—but then also make a movie about it, using some of the vast sums of money he still has left over. And so Grohl has graduated from helming Foo Fighters music videos to making his feature debut by producing and directing Sound City, a documentary delving into the 40-plus-year history of the legendary Van Nuys space that's produced albums like Tom Petty's Damn The Torpedoes, Fleetwood Mac's Rumours, and Neil Young's After The Gold Rush, while also hosting bands like Guns N' Roses, Rage Against The Machine, Fear, Cheap Trick, Nine Inch Nails, and Metallica.
