In the beginning of 2018, it was teased that a new 9th Wonder-produced EP from Black Thought was on the way. Now, we’re getting the first concrete details on that collaborative project. It’s called Streams of Thought Vol. 1 and it drops June 1, according to a teaser on Twitter. The upcoming release is credited to “Black Thought x 9th Wonder & the Soul Council.” Find that below.
The Roots co-founder has yet to release a solo album in his career. He previously linked with 9th Wonder and Styles P for the song “Making a Murderer” in 2016.
