Nas’ classic debut album Illmatic turns 30 tomorrow and to celebrate, he links back up with the legendary DJ Premier for a new song.

The pair worked together three times on that album, on ‘N.Y. State of Mind’, ‘Memory Lane’ and ‘Represent’, which are some of the best songs on the LP. Nas and Premo went on to have a great run, with songs like ‘I Gave You Power’, ‘2nd Childhood’, ‘Nas Is Like’ and more in their collection. Tonight, they add to it with a new song called ‘Define My Name’ which the QB rapper teased on social media in the week, with a post showing how long their relationship spans.

You can check out the song below. The pair have announced that they’ll soon be putting out a long-awaited collab album.
