The Native Tongues legends are hard at work on their first album in over a decade.

De La Soul have added Usher, Pete Rock, Roc Marciano, Estelle and Snoop Dogg to a list of collaborators that already includes David Byrne, Damon Albarn, 2 Chainz and Little Dragon.

“The work to complete this album has increased, but progress is still in forward motion,” they write via Kickstarter, where their latest update also includes a brief interview with engineer Bob Power.

Earlier this year, more than 11,000 backers helped raise $600,874 to fund the group’s first new album since 2004’s The Grind Date.
