Ian attended Bayside High School, with classmates (and future Anthrax bandmates) Dan Lilker and Neil Turbin.

The musical style of his playing and songwriting including fast alternate picking was also largely influenced by the German metal band Accept.

Ian states that Malcolm Young, Rudolf Schenker, and Johnny Ramone were his biggest influences to pursue rhythm guitar.

[5] As a founding member of Anthrax, Ian helped to create thrash metal in the mid-1980s alongside Megadeth, Slayer, and Metallica.

In 2005, Ian was invited by Chuck D of Public Enemy to perform "Bring the Noise" with them as part of their induction into VH1's Hip Hop Honors Hall of Fame.

During his 48 episodes as host, he interviewed guests including Ozzy Osbourne, Rob Halford, Ted Nugent, Stone Temple Pilots, Megadeth, 3 Doors Down, Sevendust, Tenacious D, and the Cult.

In June 2006, he starred in the VH1 reality series SuperGroup with Ted Nugent, Sebastian Bach, Jason Bonham and Evan Seinfeld.

[8] He joined professional poker players Phil Hellmuth and Annie Duke as one of Ultimate Bet's star pros.

On June 21, 2011, his wife gave birth to the couple's first child, thus forcing Ian to briefly depart from Anthrax's tour.

[16] The book features stories about his life including not only his adventures with Anthrax, but also with other musical celebrities such as Madonna and David Lee Roth.

He co-owned a hard rock bar called Dead Man's Hand in Las Vegas with Jerry Cantrell of Alice in Chains.

A number of Anthrax's songs were inspired by King's stories such as "Among the Living" (based on The Stand), "A Skeleton In The Closet" (Apt Pupil), "Lone Justice" and "Breathing Lightning" (the Dark Tower series).

He was seen using this guitar while playing with Brian Posehn at the Revolver Golden Gods Awards and with the Damned Things at the 2011 Download Festival.
