When Dave Grohl isn't working on his 'Sound City' documentary and jamming with Foo Fighters, Queens of the Stone Age, Them Crooked Vultures, his former Nirvana bandmates or Paul McCartney, he's hanging out with his friends in Soundgarden to direct the band's latest video.

Perhaps the hardest working man in the world of rock, Dave Grohl's latest project is behind the camera, directing Soundgarden's upcoming video for 'By Crooked Steps.' Not a great deal of information has been released about the video's concept, but through a number of pictures posted on Soundgarden's Instagram page, 'By Crooked Steps' will showcase a biker theme.

Following a motorcycle club called "Crooked Steps," the patches on the back of biker gang members depicts the grim reaper armed with his trusty scythe, and if you look closely, you'll even see some patches with a middle finger flipping the bird. Scenes depicted in the available still images show frontman Chris Cornell playing a rousing game of cards, some seedy dive bar moments and shots of Soundgarden performing 'By Crooked Steps.'

Soundgarden are set to embark on a 2013 North American tour, beginning in New York City on Jan. 16 and concluding in Los Angeles on Feb. 16. Check out the full list of tour dates by clicking here.
