The Ghana-born, L.A.-based Moses Sumney has released a second track from his first full-length record, Aromanticism, featuring a stellar line-up and stunning, soulful meditations.

"Quarrel" starts with a slow burn — just vocals over downtempo electronics and acoustics. "He who asks for much / has much to give," Sumney opens. "I don't ask for much / just enough to live," he continues, and a fluttering harp wanders in, punctuating his lyrics. Sumney tells NPR, after seeing harpist Brandee Younger on YouTube , he "flew to Harlem last summer just to record her."

The track quickly wells into a complex polyphony. Sumney's long-time collaborator, Thundercat , appears on bass, and Jamire Williams ( Miguel Atwood-Ferguson Ensemble ) joins on drums to lay down a constantly changing R&B groove. Paris Strother ( KING trio ) flips between flickering, piercing synth lines and jazz-flaired piano solos, and Cam O'bi (known for his work with Chance the Rapper , Noname , Vic Mensa ) partners with Joshua Willing Halpern ( Beck ) to produce the track.

"Quarrel" is just as thematically complex as it is musically, touching themes of isolation and pent-up anguish: "Don't call it a lover's quarrel," Sumney dares, "We cannot be lovers / 'Cause I'm the other." The accompanying visuals, done by Sam Cannon , feature a rose trapped in amber. Sumney explains that he wanted something that was simultaneously romantic and a send-up to romanticism— the rose is "preserved against its will, but still manages to decay."
