In an L.A. Times interview with Oliver Wang, Thes One described former group People Under the Stairs as defined by their “outsider-ness.” He and high-school friend Double K, who passed away in 2021, made music informed by a community of rare breaks, and that sense of not being the “cool kids” in L.A.’s turn-of-the-Aughts indie-rap scene inspired bristling, ornery raps, adding tension to the sunshine melodies. Yet time heals old grievances, and Farewell, My Friend, a tribute to Double K, is unabashedly soft and yearning. The filtered jazz-funk loop on “Young Mike and Chris Floating Free” and the disco breeze of “Mike and Chris Leave for Their First Tour” are rendered in a nostalgic glow for those halcyon years. Musically, they’re a reminder of how crucial Thes One’s sound has been to the “chill hop” aesthetic, and why he deserves to be mentioned with more celebrated beat makers like Fat Jon and Nujabes. Sequenced like a tone poem, Farewell, My Friend is nevertheless familiar territory for Thes; even as he put out PUTS albums, he also issued instrumental projects like 2007’s Lifestyle Marketing. Double K’s edgy yet good-natured thug-isms are missed. The album includes contributions from keyboardist Kat010 and bassist Headnodic, both formerly with Bay Area group Crown City Rockers; drummer Paul Caruso, and guitarist Saint Ezekiel. Their musicianship take center stage on the second half of the album, particularly “The Bell Tolls for People Under the Stairs” and “Survivor Syndrome.” Thes One released Farewell, My Friend on his label, Piecelock 70.
