Artist: Bun B feat. Sean Kingston
Song: 'That's Gangsta'
Why You Should Watch: "When we speak of "gangsta," [it] isn't always regulated to street situations," Bun B explains. "Anybody that's willing to do anything outside of the norm in order to better elevate their position, to me, that's gangsta."

Artist: Dizzee Rascal feat. Bun B
Song: 'Where Da G's'
Why You Should Watch: "Trill recognizes trill" as Bun B acts as a travel guide and gives the London-bred rapper a tour of Houston in the video for Dizzee's new single off 'Maths + English.'

We all need guidance and the DL show has taken on the heavy task of schooling all of you out there that might need a little help from time to time. Check out Bun B as he drops some words of wisdom in the DL's first installment of the new public service series: 'If We Didn't Tell You, Who Would?'

"First of all, let me say I've never set out to be a solo artist, so doing a solo album was not a natural process for me," Bun B told the BoomBox during a taping of an exclusive 16 Bars freestyle segment in our New York studio. Pimp C's death has transformed UGK from a duo to a one man show, and the 34-year-old rapper is still dealing with the lost of his friend.

"It's definitely not an easy road to walk," the rapper explained. "I know that he's in heaven, that he's in a better place and I'm going to get to see him again, and that in itself helps me."

Now that he's on his own, the 34-year-old rapper realizes that his upcoming solo project, 'II Trill,' which is due in stores on April 29, will serve as his way of keeping UGK alive.

"During the time of Pimp C's incarceration, ['Trill'] was the best way that I knew to keep the UGK name and the UGK legacy alive and to keep us out there. With this solo album, [I] understand that [I] have a solo career now," Bun said. "It's different with 'II Trill' because, with 'Trill,' it was absolute new ground. I myself had never done anything like that, so I was a little bit nervous and apprehensive at certain parts as to how this s--- was going to come across. With 'II Trill,' we know we can do it, it's just a matter of doing it better than we did before."

Pimp C, who was found dead at the Mondrian Hotel in West Hollywood, California, last week, will be remembered at a funeral service in the rapper's hometown of Port Arthur, Texas on Thursday.

L.A. County Fire responded to a 911 call at the hotel on November 4, only to find C -- one half of rap duo UGK -- dead in his bed. Currently, there's no official word on what caused the rapper's death. An autopsy was performed, but results won't be available for up to eight weeks. Officials have stated that there was no sign of foul play.

UGK -- which consisted of C, whose real name was Chad Butler, and Bun B -- were most commonly known for guest appearances on Jay-Z's 1999 hit 'Big Pimpin'' and Three 6 Mafia's underground hit, 'Sippin on Some Syrup,' as well as their latest single, 'International Player's Anthem (I Choose You),' featuring OutKast. The latter is found on their new album, 'UGK (Underground Kingz).'
