It's no secret that Kendrick Lamar demands the best out of himself with every song he releases, but we've learnt just how far he'll go to make sure his music is on point.
Speaking to Kevin Durant and Eddie Gonzalez on their podcast The ETCs, Kendrick's engineer, Derek "MixedByAli" Ali, revealed just how much unreleased music Kendrick leaves behind when he drops an album.
The pair have been working together since Kendrick's 2012 album good kid, m.A.A.d city, and since then Kendrick's made around six albums' worth of unreleased tracks, which has absolutely blown us away.
Derek says, "For Kendrick alone, let me say I think we could put together like six albums. Everyone's the same way, it's all about just understanding that you could always do something better. It's having that mindset to just strive for the best possible version of you.
"That's Kendrick's whole mind state, always striving to do better. Whether it's recording a new verse, you know he would record a whole song and get one ad-lib back a month later because he don't like how he breathed the ad-lib, y'know?" It's fair to say that Kendrick is a perfectionist - and that's why his music is so amazing.
