Siddiq Booker aka Creature (born November 10, 1973) is a New York City-based independent underground rapper, vocalist, writer and composer who works in the rap, hip hop, and afro-punk genres.

[4][5] Creature was inspired growing up listening to Grandmaster Flash's "The Message" and fellow Queens residents, Run DMC's, "Sucker MCs" on a boombox at the pool in Corona.

They work through new music live and draw inspiration from bands ranging from Public Enemy, Sly and the Family Stone to John Coltrane and Metallica.

Following that Creature had a song with Rob Sonic and Hangar 18 called "Sniper Picnic” that was featured on the Tony Hawk video game.

[6][3][17] Creature created a concert series called The Coffee Grind that featured a mix of under-represented hip hop artists with those more well known like Just Ice, Camp Lo, and Sadat X.

[18] The book explores Creature's journey of being a self-produced independent artist and how he learned creative ways to publicize and package one's work.

[8] Underdog's Manifesto includes interviews with Percee P, Duo Live and “Lucky” Logan P. McCoy and an afterword by Jeremy Glick.
