Multidisciplinary artist Jasper Marsalis makes uncompromisingly abstract yet deeply emotional music as Slauson Malone 1. His poetic, fractured reflections on death, resistance, and hope encompass left-field hip-hop, psychedelic soul, dub, modern composition, and other genres. He was a member of the similarly uncategorizable Brooklyn-based ensemble Standing on the Corner for several years, and collaborated with rapper Medhane as the duo Medslaus. He made his full-length debut with the collage-like A Quiet Farwell, 2016–2018 (Crater Speak), and contributed to albums by Pink Siifu, L'Rain, Nosaj Thing, and others. Slauson Malone 1 appeared on Warp with the 2023 full-length Excelsior.

Born in Los Angeles, Jasper Marsalis is the son of jazz great Wynton Marsalis and famed actress Victoria Rowell (The Young and the Restless, Diagnosis: Murder). While living in Brooklyn, he created abstract hip-hop beats as Slauson Malone, and joined Gio Escobar's experimental jazz/hip-hop/lo-fi group Standing on the Corner, helping to shape their demo recordings into the self-titled 2016 debut LP. Working with rapper Medhane as the collaboration Medslaus, the duo released the woozy, dreamlike album Poorboy in 2017. Marsalis left Standing on the Corner following their second album, the acclaimed Red Burns, but was later given a producer and writer credit when the band contributed to uknowhatimsayin¿, the 2019 album by Danny Brown.

Slauson Malone's debut album, the surreal, claustrophobic A Quiet Farwell, 2016–2018, was released in 2019 as part of a series of releases titled Crater Speak. The dark, collage-like release included guest appearances by Maxo, Pink Siifu, Caleb Giles, and Taphari. Crater Speak continued with the 2020 EP Vergangenheitsbewältigung and 2022 ambient release for Star. Additionally, Malone contributed to L'Rain's 2021 critical breakthrough Fatigue and albums by Pink Siifu, Nosaj Thing, Jonah Yano, and others. The project signed to Warp in 2023 and added the numeral "1" to its name, releasing Excelsior, a more refined but still enigmatic second full-length incorporating orchestral and choral arrangements on certain tracks. ~ Paul Simpson
