UTFO (which stands for Untouchable Force Organization) was an old-school hip hop group, popular in the 1980s, that was mentored by the contemporary R&B group Full Force.
 The group consisted of Kangol Kid (Shiller Shaun Fequiere), Educated Rapper (Jeffrey Campbell), Doctor Ice (Fred Reeves), and Mix Master Ice (Maurice Bailey).

 "Roxanne, Roxanne" was originally the B-side of the lesser-known single "Hangin' Out."
 Because of personal issues, Educated Rapper was absent for its second effort, "Skeezer Pleezer" (1986), which produced one notable track with the song "Split Personality."
 EMD was, however, on one album track, "Pick Up The Pace", also featured in the movie "Krush Groove".
 In 2008, “Roxanne, Roxanne” was ranked number 84 on VH1's 100 Greatest Songs of Hip Hop.

 Mentored by The Black Panthers as a youth; Paradise's lyrics frequently use social and political themes inspired by personal experiences.
 During The 57th Dynasty's early years, Paradise's lyrics contributed to their rebellious and spiritual tone.

 2 - A Dynasty Truly Like No Other" (2002) are considered landmark albums.
"In Our Lifetime" is a funk song recorded by singer Marvin Gaye, issued on his final Motown album, 1981's "In Our Lifetime".
 The title track's rhythm admittedly was taken from Rick James while the song parlayed a different message of partying with Marvin predicting the world's end as he had believed from teachings he absorbed from his father that Armageddon was approaching and that he wondered if it would happen in his lifetime.
 He says the title track as a question mark.
 In fact, the original concept of the album was to have a question mark at the end of the album title, "In Our Lifetime?"
, Motown instead took the question mark rush-releasing the album after it was presented to the label in late 1980 by bassist Frank Blair.
 The song ends ironically enough in a much somber jazz tone that was likely edited in by Motown staff.
 An earlier funk version of the song was recorded as "I Offer You Nothing But Love" for Marvin's "Love Man" album and a 2007 Odyssey Studios mix of the song ended the song without a jazz instrumental.
