"Doowutchyalike" is a song performed by Digital Underground.
 The song was released independently by the group in 1989 and later included on their debut studio album "Sex Packets".
 Produced and co-written by group leader Shock G, the song peaked at #19 on the "Billboard" rap chart in 1990.
DVS Mindz was an underground rap music group from Topeka, Kansas that was active primarily from the mid-1990s to the mid-2000s.
 The group's name stands for Dope Versatile Styles Manifested IN a Direction to Zucceed.
 The group's classic lineup consisted of four MCs: Str8jakkett, Killa The Hun, D.O.P.E., DL; and a DJ, Kutaculous.
 The group's sound was sparse, with raw beats and furious, nonstop rhyming from all members.
 While the group had very catchy material, many of its songs featured no chorus, just a sparse beat and verse after verse from the MCs.
 The group's lyrics were packed with inside jokes, mythology, pop-culture references, puns, numerology, religion, violence, and obscure references to the group's history.
 Each member also had alter egos and pseudonyms, and they sometimes rapped in those voices (For example, Str8Jakkett had another alter ego known as "Rex").
 During its decade-long career, DVS Mindz released one critically acclaimed CD, and opened for a number of notable rap acts, including Run DMC, Wu Tang Clan, Sugarhill Gang, Redman, De La Soul, Digital Underground, Das EFX, Black Sheep, and Goodie Mob.

 Filming began on November 12, 2014, in Enderby, British Columbia.
 Although screened as "Go with Me" at the Venice Film Festival in 2015, it was not released for public viewing in the U.S. until 10 June 2016.
Gregory Jacobs, commonly known by his stage name Shock G (as well as by his alter ego Humpty Hump) is an American musician and rapper, known as the lead vocalist for the hip hop group Digital Underground.

Reggie Gibson, better known as Saafir, is an emcee, producer and actor from Oakland, California.
 He is also a member of the rap group "Golden State Project" (formerly known as Golden State Warriors) with Ras Kass and Xzibit.
 Born in Oakland, California, he lived with Tupac Shakur and became a dancer for Digital Underground.
 Saafir took part in one of the most notorious Bay Area rap battles, when he and members of the Hobo Junction went against Casual and members of the Hieroglyphics Crew.
 The battle took place live on KMEL.
 There has never been a real decision as to who won the battle.
 Saafir admits that during the battle he simultaneously used premeditated and freestyle rhymes claiming during lyrical warfare a true combatant leaves nothing to chance making sure his opponents face heavy artillery and an arsenal of weaponry.
Sons of the P is the second album by American rap group Digital Underground, released on October 15, 1991.
 The album featured two hit singles, "No Nose Job" and "Kiss You Back", both of which were written by, and featured the lead vocals of Greg Jacobs (a.k.a. Shock G/Humpty Hump), and the latter of which featured multi-layered choruses and background vocals sung by Boni Boyer, who briefly worked with D.U. shortly after her stint with Prince's Sign of the Times/Love Sexy band.
 It is sometimes mistakenly reported that Kiss You Back was co-written & co-performed by George Clinton, but his name appropriately appears in the writers credit due to a sample of "(Not Just) Knee Deep" by Funkadelic.
 He did however actively participate in the writing and recording of the title track "Sons of the P", to which he also contributed vocals, and which marked one of the earliest studio guest appearances by Clinton on a Hip Hop release, preceded only by Kurtis Blow's "Magilla Gorilla" released in 1986.
 Both the album and the single "Kiss You Back" were each certified Gold by the RIAA.
David Johnson, also known as the World Famous Bushman, is a busker who scares passers-by along Fisherman's Wharf in San Francisco, active since 1980.
 Johnson hides motionless behind some eucalyptus branches and waits for unsuspecting people to wander by.
 When they approach, he shakes the bush towards the unsuspecting tourists and startles them, sometimes making gruff "oogah-boogah" noises, while in-the-know observers giggle.
 Crowds gather to watch him work, often including those he has previously scared.
 The Bushman typically operates toward the western end of the Wharf (at Jefferson and Hyde Streets or thereabouts), well to the west of the Grotto.
 Johnson used to work with or, at different points in time, as a rival to a second Bushman, Gregory Jacobs, until the death of Jacobs in 2014.
