Kendrick Lamar's 'To Pimp A Butterfly' Review Roundup

American hip hop artist Kendrick Lamar's latest music album To Pimp A Butterfly was released a week earlier than expected and surprised many fans. The album has already taken the Internet by storm and has been streamed over 9.6 million times by Spotify users just a day after it was released.

To Pimp A Butterfly addresses a number of concerns such as race, desire, madness and power.

"He kicks off the long album with songs such as 'For Free' and 'King Kunta' that reference slavery. But he hasn't turned into a lecturer or a scold. In tracks like 'U,' Lamar expresses his personal fears in a rush of rhymes so anxious, it sounds like he's about to have a mental breakdown," said Jim Farber of New York Daily News.
