LANDR raises $6.2 million in funding.

Cloud-based service LANDR describes its mastering process as “nearly foolproof:” users choose monthly or annual fee, upload the files and then tweak controls to get the desired sound. While it seems a bit too simple to us, it has some high-profile backers.

Billboard reports that Warner Music Group, Nas and the Plus Eight Equity Fund (which is backed by Pete Tong, Richie Hawtin, Tiga and John Acquaviva) are among the participants in a $6.2 million funding round.

In a statement, Nas claims that LANDR can turn out music with “a quality finish like any major label artist with a budget.” Just don’t tell the mastering engineers at London’s iconic mastering houses.
