Satriani is an American instrumental rock guitarist, multi-instrumentalist and multiple Grammy Award nominee. Early in his career, Satriani worked as a guitar instructor, with many of his former students achieving fame, such as: Steve Vai, Larry LaLonde, Rick Hunolt, Kirk Hammett, Andy Timmons, Charlie Hunter, Kevin Cadogan and Alex Skolnick.

In 1988, Satriani was recruited by Mick Jagger as lead guitarist for his first solo tour. In 1994, Satriani toured with Deep Purple as the lead guitarist. He has worked with a range of guitarists during the G3 tour, which he founded in 1995. His G3 collaborators have included Vai, LaLonde, Timmons, Steve Lukather, John Petrucci, Eric Johnson, Yngwie Malmsteen, Brian May, Patrick Rondat, Paul Gilbert, Adrian Legg, Steve Morse and Robert Fripp. He is currently the lead guitarist for the supergroup Chickenfoot. Since 1988, Satriani has been using his own signature guitars, the Ibanez JS Series, which are sold in music stores worldwide. He has also collaborated with Vox to create his own wah, delay, overdrive and distortion pedals as well as a collaboration with Marshall Amplification for the creation of his own signature series amplifier head, the JVM410HJS.
Satriani's work frequently makes references to various science fiction stories and ideas. "Surfing with the Alien," "Back to Shalla-Bal," and "The Power Cosmic 2000" refer to the comic book character Silver Surfer, while "Ice 9" refers to the secret government ice weapon in Kurt Vonnegut's Cat's Cradle. "Borg Sex" is a reference to Star Trek, which features a homogeneous cybernetic race known as the Borg. His albums and songs often have other-worldly titles, such as Not of this Earth, Crystal Planet, Is There Love in Space?, and Engines of Creation.

On the album Super Colossal, the song titled "Crowd Chant" was originally called "Party on the Enterprise". It would have featured sampled sounds from the Starship Enterprise from Star Trek. But as Satriani explained in a podcast, legal issues regarding the samples could not be resolved and he was unable to get permission to use them. Satriani then removed the sounds from the song and called it "Crowd Chant". Its ending theme was inspired by composer Gabriel Fauré's "Pavane in F-sharp minor, Op. 50". The song is used as goal celebration music for a number of National Hockey League teams and Major League Soccer teams including the Minnesota Wild (NHL) and New England Revolution (MLS). The song is also used in the 2K Sports hockey video game NHL 2k10.

"Redshift Riders," another song on the Super Colossal album, is "based on the idea that in the future, when people can travel throughout space, they will theoretically take advantage of the cosmological redshift effect so they can be swung around large planetary objects and get across the universe a lot faster than normal," Satriani said in a podcast about the song.] On the album Professor Satchafunkilus and the Musterion of Rock the song "I Just Wanna Rock," is about a giant robot on the run who happens to stumble upon a rock concert.
