Jacobs, a rapper, songwriter, and music producer, was best known as the founder of rap/hip-hop group Digital Underground. He also created the group’s “Humpty Dance.”

Jacobs was born in Brooklyn, NY on August 25, 1963. His family traveled around the East Coast before settling in Tampa, Florida.

He relocated to Queens, New York (after his parents’ divorce), where he learned to play the drums.

Upon returning to Tampa, he took a job DJing at a local R&B station. He was the youngest radio personality in central Florida. He was fired for playing the 15-minute long album version of “(Not Just) Knee Deep” by Funkadelic in a 5-minute time slot.

In the 1980s Jacobs moved to Oakland, California, where he founded Digital Underground with Chopmaster J and the late Kenny-K in 1987.

The group had radio success with “Doowutchyalike,” off their debut album, which featured the first appearance of Jacobs’ alter ego, Humpty Hump.

The music video for the album’s second single, “The Humpty Dance,” peaked at No. 11 on the Billboard Hot 100 chart. The song’s music video also featured a young Tupac Shakur (right), who rapped on the group’s single “Same Song.”

Jacobs returned the favor by producing Shakur’s breakthrough single “I Get Around,” on which he also appears as a featured artist. Jacobs also produced Shakur’s 1995 single “So Many Tears,” off his third studio album, Me Against the World.

As a music producer, Jacobs worked with legends such as Bobby Brown, Dr. Dre and Prince.

Tributes poured in on social media in the hours after the news broke on Thursday.

Digital Underground’s official Twitter page featured a quote by 2Pac about Shock G: “I look back [on my times with Shock G] with the greatest fondness. Those were like some of the best times of my life…”
