Gregory Edward Jacobs (August 25, 1963 – April 22, 2021), known professionally as Shock G and by his alter ego Humpty Hump, was an American rapper and musician who was best known as the lead vocalist of the hip hop group Digital Underground. He was responsible for Digital Underground's "The Humpty Dance", 2Pac's breakthrough single "I Get Around", and co-producer of 2Pac's debut album 2Pacalypse Now. Early life Gregory Edward Jacobs was born on August 25, 1963 in New York City. He spent most of his childhood moving around the East Coast with his family, eventually settling in Tampa, Florida. As a drummer he won the 1978 "Most Talented" trophy at Greco Junior High School, but after relocating to Queens, New York (as a result of his parents' divorce), he traded his drums in for a set of turntables upon discovering and marvelling over hip hop while the art form was still in an underground developmental stage. He was mentored in the craft by his cousin Rene Negron (a.k.a. DJ-Stretch), and their close friend Shawn Trone (a.k.a. MC Shah-T of the parody-rap group No Face) who suggested Greg use the name "Shah-G". Jacobs liked the idea, but mistakenly thought his friend said "Shock-G", and began using that name instead. After returning to Tampa less than two years later, he dropped out of Chamberlain High School to form the Master Blasters, a mobile DJ crew which featured three DJs and four emcees at its height. They performed at parties, and also for the crowds at Riverfront Park's outdoor Sunday gatherings, eventually capturing the interest of Tony Stone, a program director at WTMP radio, which was the city's primary R&B station. Tony offered Jacobs, who was sixteen at the time, a job DJing on the air, and for a short while, as "Gregory Racker", he was the youngest radio personality in central Florida with a regular time slot. After being fired for playing the fifteen-minute-long album version of "(Not Just) Knee Deep" by Funkadelic in a five-minute time slot, and also after tensions with his father escalated, Jacobs found himself backpacking the United States for a few years, drifting through odd jobs and petty criminal adventures. It was during this excursion that his focus switched from DJing to keyboard playing, and while utilizing piano practice-rooms at music stores and colleges around the country, he effectively taught himself to play the piano.
