For the latest episode of Earl Sweatshirt’s Red Bull Radio show, Earl Sweatshirt Stays Inside, the rapper/producer was joined by his former tour mate Solange Knowles. The sit-down was equal parts random and delightful.

The artists discussed a wide range of topics, ranging from mudras and conspiracy theorists to wigs and Ariana Grande. Solange praised the 25-year-old singer on her new album. “Sweetener is that shit,” she told Earl. “It feels so good, summer vibes, really knows how to use her instrument. Just overall fire.”

The episode wraps up with an appearance by Gio Escobar of Standing on the Corner, who embarks on “an hour-long journey through the space-time continuum” before celebrating John Coltrane’s birthday.

You can watch the two-hour episode via Red Bull Radio above.

The episode airs just days after Earl teased the follow-up to his 2015 album, I Don't Like Shit, I Don't Go Outside.
