There's a new Kendrick Lamar album out. Fans who were wondering when Lamar would release more music got quite a pleasant surprise Thursday night, when the Grammy-winning artist unveiled "Untitled Unmastered," featuring eight new tracks with no fanfare or build-up. As for why the album was released this week, fans may be able to thank basketball star LeBron James for that, as he tweeted at Lamar's label boss, Anthony Tiffith, to get the new music out following Lamar's showstopping performance at the Grammys last month.
