Before today, perhaps the only thing Courting and RXK Nephew had in common were their shared status as Stereogum Artists To Watch. Today, their worlds collide, as the genre-jumping Liverpool indie band welcomes the Rochester street rap surrealist onto a new track. It’s called “rollback freestyle,” and, after a brief buildup, it finds Neph kicking out bars like “I’ll start tweakin’ like Kanye/ Might paint your hair like Dennis Rodman” over a skronking noise-rock backbeat that reminds me of Gilla Band. It’s the kind of track I imagine Danny Brown hopping on, and it’s giving me nostalgia for the indie-blog music landscape of the 2010s.
