(AllHipHop News) T.I. penned a letter to his fans from behind bars at the Forrest City, Arkansas, on the day his seventh album No Mercy hit stores. In an upbeat letter, the Atlanta rapper said that No Mercy is the most “intimate” installment of his life story.”I must admit it takes a lot to go through as much as I have and still keep the love in your heart and in your art,” the imprisoned rapper said. “But at the end of the day, if that’s what it takes to produce the music that keeps the world of hip-hop evolving on it’s axis….Then even the lowest of the lows of my life was all worth it.”No Mercy features an all-star cast of Hip-Hop artists and includes cameos by Kanye West, Kid Cudi, Young Dro, Drake, Pharrell, Eminem and others. “Thanks again for your prayers, your time and attention,” T.I. said. “And remember….It does’nt [sic] matter how long it’ll be before the next time you see me. What matters is that I’ll be a better man before that time comes. The longer I sit, the smarter I get.”According to T.I., he is hard at work on a new untitled project, which said he planned on unveiling in the coming months.
