DVS Mindz: 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.

Sons of the P: 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.

World Famous Bushman: 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.
